New England's Roadside Ecology with Tom Wessels


Notable Terms to Learn:

"Root Graft" - in regard to trees, the term refers to morphological interconnections, i.e., growing together of contacting roots of the same tree species (self-root grafting).  Among trees of different species, it is called intraspecific root grafting.  (I would assume that most of the time, these interactions happen below the surface.)

Along these same lines, natural limb-grafting and trunk-grafting can take place as well, in places where limbs and trunks have been in close contact for years (perhaps decades).  (I have photos but finding them is another issue.)

"Callus Wood" - The initial growth response to a tree wound, from storm damage or tree cutting.  If the tree is healthy, then the Callus becomes overgrown with "Woundwood" (in which the cells have become more specialized (differentiated and lignified).  In the Figure 1 image, the light-colored ring around the cut area is likely the "Woundwood".

Here is a good article on the subject.  Here is an online discussion.

Vanlife Conversion Update: May 2021- 1995 Chevy G20


(I don't think I have posted this one before.)

For the time being, perhaps to keep me motivated, I may be dropping van videos into the mix of Geology and Ecology videos and sporadic posts of my own.  Today, I did purchase some samples of wood to start composing some Van Go! changes.

In this previous post, aside from the "visiting video", i.e., not my own but pertinent to the subject, I posted some of my thoughts about our initiation into the world of van camping and what else is on my mind as far as changing some interior features.

Welcome to 2022! - Part 1

In order to find and focus on the Positives, e.g., the personal successes and shortfalls (and what we have learned from them) of 2021 and plans for 2022, ...

In this time of seemingly-increasing madness, our own lives are the lives mostly-likely influenced by our own personal choices and deeds.  Positive choices can provide a modicum of serenity and positive outcomes (even small ones) can provide a sense of achieving "small victories", even if they are only victories over our own bad habits and self-doubts.  

There has been some research that suggests that seemingly-small accomplishments may provide to our brains little doses of Oxytocin, i.e., that relieved feeling of "Hey, I got that done." and provide a basis and confidence for addressing another self-identified concern or task.  Especially if you sense that someone else had doubts that you would actually finish the task.  (Even without saying it, in your own mind, you "proved them wrong.")  

If you "begin" a series of tasks with one or two of your own choosing, when you finish them, the minor emotional lift may help you when you embark upon more-difficult, involved, and/or unwanted (but necessary) tasks, as well as any "unexpected" tasks.  

An example of an "accomplished goal" of 2021 - though not an "official New Year's Resolution" (that often fall by the wayside) - was the outdoor walking program suggested by my wife and begun last January.  As I hadn't engaged in a focused walking program since my "mall walking" of 2016, with my doctor's approval, I began gradually, only walking 12.35 miles that first month.  

With the initial "every other day" routine getting my leg muscles, feet, and knees acclimated to walking, within a week or two, I began walking every day (as my schedule allowed).  Within a short time, I silently resolved to average 67 miles (= to my age) per month for the entire year, a distance of 804 miles.  Except for four months, I exceeded that goal every month.  

Those exceptions - January, June (due to foot pain resolved by a Podiatrist visit), August (van preparation and embarking upon our 22-day "Great Northern Adventure"), and September ("vacation recuperation" and Georgia heat and walking re-acclimation) really "pulled my average down", necessitating a renewed sense-of-purpose.  With the cooling Fall weather and walking 124+ miles in November and 104+ miles in December, I reached my 67 miles-per-month average on December 30th. 

Benefits of the walking program were noticed by my doctor and friends.  After a diet-related 2020 weight loss of 15 lbs. (225 to 210), I was managing similar 2021 weight loss, until the dreaded late-November to New Year's Eve time, "where diets go to die" (my wife is a great cook).  Still, I managed to end the year with a 5 lb. (210 to 205) weight loss.  (Not quite I what wanted, but at least two years in the right direction.)

To close this New Year's blather, aside from the above benefits, a downside to my 67-miles-per-month walking program was in my book-reading regimen.  I usually read at least one book per month, but in 2021 I only managed four books total, plus two more in progress.  In another post, I will review all six books, all of which have ecology-related themes (sometimes indirectly though).  In 2021, five of the six books were purchased from local used bookstores and thrift stores, and only one of the six books had I even heard of before.

I also plan to post more "original content" material and not so much of other peoples' Youtube videos.  The problem is, "original content" takes time to write and edit and I want a somewhat steady stream of posts, to keep myself on track to resume a writing project (about my 1974 Road Trip) which was suspended after my wife's September 2019 car accident, in which she was rear-ended at an Athens, Georgia red light.  

Since 1979, she has been rear-ended eight times and has also broadsided a "stop sign runner", i.e., none of them were her fault.  As she is in her mid-60s, there has been a cumulative, negative effect on her overall health, which is why it is difficult for her to drive or ride for 6+ hours in our van, despite the seats being comfortable.  This limits our vacation travel and is a reason why we missed visiting Devils Tower while we were in the Black Hills area.

A Reminder About What Geology is...

A common misconception about Geology is that it is solely about the study of rocks and to a lesser extent fossils.  Of course, it is, but it is more, much more.

Over the years, I have spoken with numerous people that confessed having had an interest in Geology, but were discouraged by family members or by their own doubts as to "What will I do with it after college?"  (Perhaps thinking that it is "only about rocks".)  In a bit, I will get to the diverse employment pathways that Geology can provide. 

Geology is the study of the Earth, its processes, the results of those processes, and its history.  The word "Geology" is derived from "Gaia", the Greek word for Earth and "Logos", the Greek term for Science Knowledge. 

"Earth Science", despite being a longer term - in my opinion - is an apt and appropriate substitute for "Geology".  In fact, "Earth Science" seems a bit more encompassing.

For academic purposes, the two primary branches first presented to students are Physical Geology and Historical Geology. 

Physical Geology is about Earth processes and the results of those processes and is usually taken first when both classes are to be taken.  As for processes, these include the Rock Cycle; Igneous and Metamorphic Processes; Weathering; Erosion; Deposition; Coastal Processes; basic Mineral and Rock Identification; Plate Tectonics;...

Historical Geology is about the History of Geology; the people involved in the conceptualization of Modern Geology, over the course of the last 300 years, i.e., the Founders of Modern Geology; the Geologic Time Scale and its development; Sedimentary Processes; basic Sedimentary Rock Identification; the History of Life; and of course, Fossils.

To start your academic journey (but not to scare you), there are important "subsidiary" classes that can be of help, subject to college and academic advisory opinions.  In my case, my undergrad requirements included: Geography, Biology, three Chemistry courses, three Physics courses, Trigonometry, and two Calculus courses (gasp!).  (Because of my struggles with Math, the Physics courses and Math courses "put a real hurt" on my undergrad GPA.)  I had classmates that downgraded from a Bachelor of Science to a Bachelor of Arts to avoid the worst of the Math requirements.  

Suggested Elective Courses that helped were Land Surveying, Scientific Photography, and Technical Drafting.  The Surveying class helped with later Geologic Mapping classwork and the Technical Drafting helped with the actual sketching and drafting of maps.  Now, CAD (Computer Assisted Drafting) has supplanted the drafting by hand, but being able to sketch your own basic map, at least over a Topographic map, is still a vital skill that Field Geologists need.

Not to swamp you with "...ologies", but pertinent branches of Geology (or closely related disciplines), for those suited to the pursuit of this science, include (in no particular order):

Paleontology - the study of Fossils
Palynology - the study of Fossil Pollens
Geomorphology - the study of Landforms
Glaciology - the study of Glaciers
Petrology - the study of the history of a particular rock type
Petrography - close analysis of the minerals within a rock
Oceanography - the study of Oceans
Stratigraphy - the study of Layered Rocks
Structural Geology - the study of Deformed Rocks
Hydrology - the study of Water
Economic Geology
Petroleum Geology
Physical Geography
Cartography - the making and study of maps
Geophysics
Geochemistry...

If in a situation where a double major is possible, pairing Geology with Biology, Geography, Forestry, Engineering, Meteorology, or Law could provide a number future options.

Future posts will explore how Geology affects Ecology, the Environment, Climate and Weather, Soils, and other things.

From Rocks to Trees

After the normal Winter doldrums, coupled with a year of the Pandemic and political chaos, many of us want to get outside as the weather warms and improves.  With the hoped for future arrival of Spring in a few weeks, I decided to switch - for a while - to "Life Sciences" outside of Geology, partially for my own reasons.

During this time, I still intend to intersperse Geology, Ecology, (and related subjects) and Ecology, videos with random periods of notes and reflections.

Willie Nelson - "Nothing I Can Do About It Now" [Live from Austin, TX]

 In my ongoing series: "Down Memory Lane, Lurching I Go, Again ... Parts 1 - 7", I have expressed repeated lamentations about not finishing my part of this Eagle Mts. project, (though I did go on to do a Master's Thesis in another volcanic setting associated with the Aden Basalts in southern New Mexico, a few years later.)

In light of these disappointments, I had posted an apt Willie Nelson philosophical view of this part of my past, but the video of "Nothing I Can Do About It Now" was withdrawn.  The disappointments will always remain, but they will never overshadow the learning adventures, memories, photographs, and experiences I enjoyed 41 years ago.

Revisiting the mountains and camping again at East Mill is a "Bucket List" item that can likely never be fulfilled - for a variety of reasons.  One reason, at age 65+ one simply shouldn't redo some of the things done at age 24.  Grinding around those mountain roads in 4-wheel drive at 10 mph, getting stuck in loose rocks, and having to dig and wedge rocks under the tires - to escape - for example, is the stuff of memories. 

So, it is best to focus on the learning opportunities of things that happened "then" and recounted "now".  Things that include Geology, Geography, Ecology, Environmental Science, Photography, History (I didn't even mention the roles Eagle Spring played (Underwood, 1980) at the northern end of the mountains, as a stagecoach stop and a place in which the "Buffalo Soldiers" took shelter as they were being chased by Victorio's renegades), ...

In that regard, I hope something positive is gained amidst my blatherings.

Ecology and Environmental Science Posts

Here is the "search link" to past posts in which "Ecology" was mentioned.

And here is the "search link" to past posts in which "Environmental Science" was mentioned.

Though related, these two disciplines are not the same.  Ecology is a "branch" of Biology relating to organisms and their interactions with their surrounding Ecosystems, including how those organisms themselves influence their resident Ecosystems.

"Environmental Science" is more of a "hybrid" discipline, incorporating elements of Biology, Geology, Physics, Chemistry, History, Human Culture, Politics, Economics, i.e., looking more at the "big picture" of the natural and the human-influenced aspects of the Earth.  

William Least Heat-Moon Intro

For the next few days, I will be paying respectful homage to author William Least Heat-Moon (Dr. William Trogdon).  If you are not familiar with him, he is considered a modern-day "Dean of American Travel Writers" (in my humble opinion).  His demographic background is primarily English, Irish, and Osage.

As a first-time writer, his 1983 book "Blue Highways: A Journey into America" came about following the 1978 loss of his teaching job at the University of Missouri - Columbia and his unwanted separation from his first wife.  

From memory (I last reread the book in 2014), the confluence of these painful events seemingly triggered a period of introspection while he "plotted his next move".  Again from memory, it was during this introspection that he reconnected with his Osage roots.

Faced with his uncertain future, he sold off his possessions and scraped up funds to buy a 1975 Ford Econoline van, built in a bunk, added portable toilet, and some other basic travel amenities, and set out on a 3-month long journey that covered 13,000+ miles on back roads, i.e., the "blue highways" in the Rand McNally road atlas, steadfastly avoiding interstate highways and large cities when possible.  In the spirit of his Osage heritage, he named the van "Ghost Dancer".

He made a point of visiting rural small towns with unusual names, e.g., Dime Box, Texas, and Hachita, New Mexico, seeking out and chatting with locals.  If he saw a long-closed store or cafe or an abandoned bus or train station, he would ask about it.  

In this and subsequent books, aside from local history and culture, he did touch upon other subjects within the realm of "Ecocentrism", wherein he weaves together nature-related subjects, e.g., Ecology, Geology, Botany, with local agriculture, history, industry, and economics into the narrative. 

Initially, as there was a level of semi-isolation on these "blue highways" and the towns thereon, some of the people were unsure about "talking with this stranger", but his manners and methods seemed to put them at ease, to the point where they "opened up" to him, while he subtly kept notes.  

Perhaps because they were "speaking with a friendly stranger" (and felt somewhat anonymous), Heat-Moon was often surprised by the "secrets" they would tell him.  Perhaps it was because of the nature of "everybody knowing everybody else's business" in a small town, this was an opportunity to "spill secrets" to an "outsider" without your aged Aunt Martha or the local "Gladys Kravitz" finding out.

By his own account (in the video to be posted tomorrow), the journey took about 100 days.  As mentioned above, at that point he was a first-time writer, an "unknown quantity" to the book editors and publishers of the time, in a genre - American travel by car - that was not seen as glamorous (nor profitable). 

By the time he was "finished" with the project (if one ever is), by his video account, he went through ten drafts.  By his own estimates, from 1978 until the book's 1982 publishing, he spent 1500 days describing the 100 days of his journey.  The follow-up book to "Blue Highways" (though not chronologically) is "Writing Blue Highways" (2014), about the herculean obstacles facing a "rookie author".

Almost 40 years after its 1982 publishing, "Blue Highways" continues to be hailed as a "masterpiece of American travel writing", influencing many people to embark upon their own exploratory journeys across and around the country and in some cases, make a record of that journey, by video and by blog, two media that did not exist contemporaneously with "Blue Highways".  (From his video though, it seems that he is happy making notes on a composition notebook or perhaps a legal pad.)

My first reading of "Blue Highways" took place sometime in the latter months of 1982, if memory serves me correctly.  My former roommate Dave (my 1974 Road Trip cohort) was by then working in a bookstore in a major Northern Atlanta mall and he highly recommended it.  I enjoyed the book, though I was unaware of any subsequent Heat-Moon books until I did a computer search to purchase another copy of "Blue Highways" in 2014.

In 2014, as the fourth-decadal anniversary (40th anniversary) of the 1974 Road Trip approached, I reread "Blue Highways", which inspired me to consider writing my own narrative about the 1974 Road Trip.  Aside from that resurgence of a desire to write, I also had a desire to read more of Heat-Moon's books, in no particular order.  

Heat-Moon's books are so well-detailed that once immersed within one, (paraphrasing a YouTube comment), the reader is "almost afraid of finishing it".  Actually, as they are non-fiction, I wish the books each had an index, so I could look up particular passages and terms to reread and refresh my memory.

A brief bibliography of the books of William Least Heat-Moon (spanning parts of four decades) that I have read follows:

  • Blue Highways: A Journey Into America. (1982) 
  • PrairyErth (A Deep Map). (1991)
  • River Horse: The Logbook of a Boat Across America. (1999) 
  • Roads to Quoz: An American Mosey.  (2008)
  • Here, There, Elsewhere: Stories from the Road. (2013) 
  • Writing Blue Highways: The Story of How a Book Happened.  (2014)

Here is a link to a C-Span Program about "Blue Highways", apparently from 2012.

There may be an upcoming post or two about the book that followed "Blue Highways", "PrairyErth", in 1991.

I Wish I Could Go Back to Kansas - Part 2

 Returning to Kansas for a few days of exploration and photography has become a sort of "Bucket List" (or Geo-Bucket List) goal. 

As recounted in Part 1, since 2014, I have been immersed in a writing project, with the first goal being the production of an interesting narrative about two "crossroads events" in 1973 and 1974.  These events were a 1973 Western family vacation (the last one for the four of us - Dad, Mom, sister, and me), followed by my 1974 Western road trip with my college roommate. 

Both of these events were influential towards my moving 1500 miles from home in 1977, to attend graduate school in El Paso, Texas.  Events that followed included meeting my first wife (1983), my first marriage (1984), adopting our daughter (1986), graduating from the University of Texas-El Paso with a Master of Science degree in Geology (1990), and us moving back to my native Georgia (1991).  

The genesis of this project was "decadal anniversary-induced nostalgia", triggered by the 40th anniversary of the 1974 road trip, and continuing through a time of significant life changes, career plans/expectations fizzling out (2013), being widowed (2015), my daughter's family moving to Phoenix (2015), being given a used Digital SLR camera by a friend and then buying a new Pentax K50 (2015), engaging in three Atlanta-to-Phoenix (and back) driving trips (2015 and 2016), meeting my second wife (2016), my daughter's family moving back to Georgia (2017), and getting remarried (2017).
  
As recounted in Part 1 of this posting, the 2014 rereading of William Least Heat-Moon's "Blue Highways" inspired my writing efforts.  Other of Heat-Moon's books subsequently read and enjoyed included (in no particular order) "Here, There, Elsewhere"; "Roads to Quoz"; "Writing Blue Highways" and in 2019, "PrairyErth" and "River-Horse".  Of these books, "PrairyErth: A Deep Map", published in 1991, is the most profound in terms of its quadrangle-by-quadrangle detailed analysis of Chase County, Kansas.  As defined by Wikipedia, a "deep map" is "a map with greater information than a two-dimensional image of places, names, and topography."  

Figure 1.  Monument on I-70.  Image by B. Masterson

Chase County, roughly between Topeka and Wichita, is within the "Flint Hills Ecoregion" and hosts the Tallgrass Prairie National Preserve.  Heat-Moon's intense deep-map coverage of the geology, ecology, history, culture, botany, and geography of Chase County and the uniqueness of the Tallgrass Prairie Ecosystem is credited by some as drawing the attention needed to create the National Preserve.  Formerly covering an estimated expanse of 400,000 square miles, agriculture has inadvertently reduced the Tallgrass Prairie Ecosystem to a fragmented remnant of what it once was.

The major hurdle to bringing this writing project to fruition is fashioning a suitable format. Adversarial considerations include; 1) The road trip took place 45 years ago; 2) There was no travel log kept, as we were 20 years old and not given to thinking about legacies and such; 3) Memories are fading; 4) There are few - if any - surviving Kodak Instamatic photos; and 5) An attempt was made to save the marked 1974 AAA maps, but that ended with a 2011 home renovation when the maps were inadvertently discarded.

As stated in Part 1, if I can achieve a satisfactory solution to the "Kansas chapter" of my narrative, it should serve as a template for the remainder of the recounting of the 4-week, 8800-mile journey.  As current conditions stand, in terms of health concerns, family obligations, and finances, a retracing of this route does not appear likely in the near future.  Though a "virtual journey" format with flashbacks and vignettes may serve the purpose.

Down Memory Lane, Lurching I Go, Again - Part 4

 [While doing "series posts" (consisting of Part 1, Part 2, ... ), I have been guilty of posting a Part 1 and then getting distracted and not completing planned subsequent related posts.  As for the prior parts of this thread, please scroll down.]

As previously mentioned, despite the regrets of not having finished this project and failing to inform myself of what my cohorts learned, over the years I have used some of my scanned slides (and memories) as Educational Resources, as seen with the labeled images (Figure 1) and suggested discussions below.

In an attempt to resurrect my portion of the project and to spend some "really quiet time" with only the sound of the wind and my thoughts, I visited the Eagle Mountains either in the Fall of 1979 (or was it 1980?), by myself.

As usual, I checked in at the ranch house to verify it was still OK (it was).  While chatting with the caretaker, he mentioned that the remnants of a hurricane had "wandered up the Rio Grande Valley" from the Gulf Coast and that it "sat" over the Eagle Mts. for a weekend, during which time they got 22 inches of rain (courtesy of "Orographic Lifting" - my conclusion).  [Usable in Weather and Climate discussions.]

(I suppose by examining Gulf of Mexico weather records could help estimate the date, but it doesn't matter.)  He advised me of this as "some of the roads didn't exist - in a usable manner - anymore" and he didn't have the proper equipment to fix them.  [I guess the owner in Houston was trying to decide if fixing them was worth it.]

 Figure 1A.

The text box (in the above image) obscures the roadway we used in 1978 in the NE quadrant.  This was a normal arroyo (dry canyon) crossing, down-gradient from a canyon draining part of the "highlands".  Though this wasn't part of my 1978 field area, I had wanted to explore the more-accessible parts of the NE and SE quadrants and so some more photography.

The image below shows the "roadus interruptus" within an "inner montane valley".  It illustrates the poorly-sorted nature of valley alluvium, deposited by "normal" seasonal flooding versus the 4 feet (+/-) of rapid down-cutting from a single catastrophic flash flood.  At the base of the vertical cut, you can see a small "apron" (talus cone) starting to form, as part of nature's re-establishment of a "natural angle-of-repose" for this range of clast sizes.  

[These considerations are usable in discussions of "Cycles of Erosion and Deposition"; "Changes in Flood Velocity and Capacity" due to "Gradient Variations" and degree of "Valley Confinement"; as well as "Soil-Moisture Retention" due to this being on the east side of the mountains.  Suitable for Physical Geology, Hydrology, Weather and Climate, Environmental Science, and Ecology.] 

 Figure 1B.

At the time I was taking this above photo, I wasn't thinking of educational resources or scholarly discussions, I was thinking "Well damn, I will not be doing much exploration in this area of the NE quadrant".  With that, after exploring what I could, I returned to the comfort of the "home base" at East Mill.  (This autumn photo below was probably taken at that time.)

Figure 2.  (Looking approximately Northeast.)

[Please forgive the dust spots on the sky portion of the photo.]

East Mill is a special place for me, even after not having visited it in 40+ years.  Other than a distant train passing miles away, across Eagle Flat, and random airplanes (some to be discussed below), all you could hear was the wind.  So calming as to be spooky at night, when alone.

A weather-related memory stands out amongst the East Mill events of the summer of 1978.

Within the Desert Southwest, usually in early-July, the summer heating of the continental U.S. landmass triggers a "quasi-Monsoon Effect", drawing in moist air from the Gulf of Mexico and the Gulf of California.  We welcomed the appearance of clouds over the mountains (Orographic Effect), as they brought us some shade.  But often that shade was followed by thunderstorms that forced us back to East Mill.

One afternoon, with active clouds in the area, we had "knocked off" and eaten dinner early, as we expected storms.  

[In the view shown in Figure 2, directly behind us, in the Red Light Bolson was the Rio Grande, cutting across at a NW-to-SE angle.  In Mexico, the term "Rio Grande" is not used until downstream of the confluence of the "Rio Conchos" with the "Rio Bravo" ("Rio Grande" of American usage).] 

With an hour and a half of daylight left, a small but intense thunderstorm, that probably began in Mexico, crossed over the ridge west of East Mill, and for about 10 minutes we were treated to heavy rain and lightning strikes within a quarter-mile.  We both piled into my truck and backed up-slope for maybe a 200 yards, to get a little further away from the windmill.

After the storm was "finished" with us, we returned the truck to its normal position.  We stepped out and enjoyed the cool, freshly-washed air.  As the storm trundled across Eagle Flat, then the Carrizo Mts., and across I-10 towards the Beach Mts. (NW of Van Horn), something happened.  It seemed to stop moving.  After a few minutes, it became apparent to me that the storm had reversed direction (by 180 degrees) and was coming back for another noisy visit.

I said "It's coming back.", to which Dan replied, "That's impossible!".  We argued briefly, then I decided to shut up and let the storm do the talking.  A few minutes later, Dan had to admit, "The storm is coming back ... "  

Sure enough, the damn storm drifted about 10 - 15 miles northeast, before the winds changed and pushed it back for Round 2.  We again backed the truck up the hill and watched as the storm repeated its performance, after which it traveled back over the ridge and returned to Mexico.  And with that, our Meteorology lesson in "the Movement of Convection Thunderstorms" was over.

I regret having lost touch with Dan.  If memory serves me correctly, he may have been from upstate New York.  He had a rather laidback attitude about things for a northerner.  I only heard him cuss twice, both times during our being set upon in the Eagle Mts. - at different times - by plagues of gnats and then wasps.  No fellow grad students had ever mentioned being besieged by either.  

When the gnats were at their peak, it seemed that they were desperate for moisture to the point of getting it from your eyes, nose, and mouth, driving Dan to cussing and stating that he was "ready to quit Geology and go sell insurance".  Oh, the heresy!  During the plague, we discovered that the gnats were victimizing other mammals as well.  One day, Dan managed to quietly walk to within 6 feet of a rabbit, because it was rubbing its front paws over its nose and eyes in search of relief.  It finally noticed him and hopped off.  It wasn't until we got a good rain that the gnats subsided.

Sometime later, we gradually started seeing a growing number of reddish-orange wasps flying about.  As they flew closely around us, their behavior seemed more about curiosity than aggression, perhaps they were asking "Well, did you bring us something to eat?".  As luck would have it, we had forgotten to bring any wasp treats.  Dan's second episode of cussing followed one of the curious wasps crawling into his backpack and when he reached in for something, the wasp demonstrated that it COULD sting if it needed to. 

[Sorry, still compiling the list of References.]

My Background - Part 3

 Part 1 and Part 2 were posted on prior days.  [I present these memories for the sake of science education and as a way to encourage other folks to chronicle influential events and time periods in their past.]

University of Texas-El Paso - Geology, Geography, Geophysics, Geochemistry (1977 - 1990)

As I was finishing up my B.S. degree at Georgia Southern, our professors had told us to "leave the southeast and see some different geology".  I applied to 4 or 5 middle-sized Geology grad schools (with reasonable tuitions), in other parts of the country, e.g., Carbondale, IL; Rolla, MO; Bozeman, MT; Pocatello, ID; El Paso, TX ...


Perhaps because of my 1973 and 1974 western travels, I was biased towards the Midwest or West.  Likely because my GPA was wounded by the Math, Physics, and Chemistry courses I HAD to take (and by my sometimes wayward ways), the University of Texas-El Paso was the only one to accept me.  (After hearing later winter weather reports, especially about Bozeman and Pocatello, I was glad that El Paso was my new residence.)  

The exact date of my arrival in El Paso has been forgotten, but it was a few days before registration.  Other than my Dad giving me the name of one of his Army buddies, I knew not a single person in the city.

Other than snow covering I-20 somewhere west of Fort Worth and some worrisome moments on U.S. 78 in extreme west Georgia, the journey was fairly routine.  I rolled into town on a late afternoon and stayed at a motel on North Mesa Street.  The next morning, I checked in with the Geology Department, just to let them know I was around.


How I managed to find that tiny, basement apartment at 1201 1/2 Randolph Street, on that first afternoon is an enduring mystery.  It was only $85/month and I was pleased with my success.


Spring Semester of 1977 turned out well, with a 3.6 average, including "A's" in Geomorphology and Stratigraphy.  I had made friends with some of my classmates and my joining the Beer Can Collectors had added some more friends.  The biggest surprise was in the dust storms that seemed to accompany each passing weather front.


My first Summer in El Paso was occupied by a 10-week Geology Field Camp, which entailed an intense introduction to the local geology (for the visiting students), reviews of geologic-mapping methods, and an intense introduction (for me) to the dry heat of the Chihuahuan Desert.   After the end of the fieldwork, there was a 10-day field trip through parts of the Four Corners states (NM, AZ, UT, and CO).

After the course was over, I gave a ride back to Atlanta to a field camp classmate from the University of South Carolina (that I failed to keep in touch with).  We took turns driving the 1,500 miles straight-through and I dropped him off at the Atlanta Greyhound station 38 hours later.  My only request (demand?) of him was that we take the southern route (I-10 to I-59 to I-20), so I could pick up some Shiner Beer and Dixie Beer.  That route was about 100 miles longer, but when you don't sleep anyway, what is two more hours?  It also gave me a good first-look at the Edwards Plateau Cretaceous limestones.

Due to continued distractions, I did OK in grad school, though a few of my grades should have been better.  I had been a "late bloomer", sometimes lacking in self-confidence.  When I fell in love for the first time in mid-1977 (and it crashed and burned in early 1979, I took it way too hard and dropped out of grad school).  That included abandoning my original Thesis project in the Eagle Mts., Hudspeth County, TX.  

[Walking away from grad school was a mistake, but as I fully intended to return, I didn't entertain any thoughts of returning to Georgia.  In the interim, I did odd jobs, bought and sold beer collectibles, and bought and sold mineral specimens when I traveled.]

It wasn't until I met my first wife Marla in early 1983, that I truly had a focus to my life and when I re-entered grad school, my grades were much better.  (During my second time around, my earlier courses started to "expire" due to a 5-year limit, so I had to retake them while getting married, adopting our first child, and working part-time.)

Resurrecting My Thesis

My original Thesis project had been in the Eagle Mts., as recounted herehere, and here.  My crashed and burned love life interrupted that one.  

My new Thesis, starting about 1985, was of some mystery craters in the Quaternary Aden Basalts, WNW of El Paso, within the Potrillo Volcanic Field in southern Doña Ana County, NM.  The craters had been shown to several visiting Geologists, including the respected Dr. Aaron Waters, who stated (in the early 1980s), that he didn't know what they were.  Nowadays, we know them - from Hawaiian research -  as Lava Tube Shatter Rings (Tim Orr, USGS).

Within the fissure-erupted Aden Volcanic Field, in the NW part of the flows is Aden Crater, a late-stage small shield volcano (the crater of which is about 2,000 feet across).  [Some photos are labeled for educational purposes.]

The five "craters" associated with Aden Crater are characterized by a roughly-circular to lobate encircling boulder rampart, with a collapsed inner floor. 

 Figure 1.  Index map of NW Aden Basalts.  (Perhaps due to a buried fault, the "Aden Rift" makes an almost-90 degree angle to the East.)  Craters #3, #4, and #5 were on this second segment.

 Figure 4.  Aerial photo of craters (Lava Tube Shatter Rings) #1 and #2, approximately 1 km (S 65 E) from Aden Crater.  (Photo by Tom Rollag & Assoc.)  Due to the size, Crater #1 was selected for more detailed descriptions.

As we had discovered nothing in the mid-1980's literature search, we had no idea of what to call them.  My interpretation was that the boulder ramparts were heaped up by explosive activity, followed by lava lake filling of the craters.  After eruptions ceased, the lava lakes collapsed, yielding the present morphology.

There are plenty of interesting volcanic features to see in the area.  This tiny Spatter Vent is just outside Crater #1.

After Graduation

After completing my M.S., I had a yearning to get closer to home.  While examining strategies, I took one or two Education courses, in case I decided to pursue teaching (Marla was a teacher).  I checked around Austin, TX, but it seemed that there was a temporary lull in the "oil-based" Geology job market and the "Environmental" job market hadn't really taken off yet, as I had heard it had in the Atlanta area.  

UTEP did not yet have any Hydrology courses in the Geology Department in 1990, the Hydrology course I took was through the Engineering Department (or was it Chemistry?).  Hydrology (the study of Water and its characteristics and habits) is one of the most important components of Environmental Science and Ecology (related fields, but not exactly the same).

So the choice was made in early 1991, to move my family closer to the Southeast...

Recurring Themes on this Blog

 For any new visitors, not for the sake of redundancy, but rather for the sake of memories, and because of familiarity, there are recurring themes on this blog, perhaps more when I am drifting into nostalgia and/or melancholy.  (I plan to add some links to existing posts.)

In no particular order they include:

  • My Background.  Some of the training, experiences, and events that "make me tick".  As I enjoy most "fields" of Geology, I straddle the fence between "Hard Rock and Soft Rock Geology".  [Meaning that the adherents of both camps don't entirely trust "fence straddlers".  Maybe I'm that way because I grew up with both dogs and cats, in a semi-rural setting where there was room for both.  IOW, neither "dog people" nor "cat people" entirely trust those with "divided loyalties".] 
  • Travel within the "lower 48" states, including Field Trips.  (I prefer driving instead of flying when time permits.)  Two 2015 round trips between Atlanta and Phoenix, then one 2016 round trip.  
  • 1973 Family Vacation and 1974 Road Trip (both west of the Mississippi).  These two are related, plus they helped me gain the confidence to move 1,500 miles away from home to go to grad school in early 1977.  
  • Eagle Mountains, Hudspeth County, Texas.  In 1978, I began a planned Master's Thesis Project in the Eagle Mountains but got side-tracked the following year due to personal issues (broken heart and all of that).  I spent 10 weeks there in the summer of 1978.
  • Aden Crater and Aden Volcanics.  This was the area for my completed Master's Thesis Project in the late-1980s.  Though my fieldwork made me weary of "those endless basalt flows", I long to revisit and photograph some of the things I missed before, though in cooler weather.
  • El Paso Region/Chihuahuan Desert.  Lived there between 1977 and 1991.  Numerous field trips - official and impromptu - were taken in the western Trans-Pecos region.  There is also a strong desire to revisit and rephotograph geologic features there.
  • Phoenix, Arizona area.  With both my family and my first in-laws, I have had family connections with Phoenix for 60+ years.  I briefly considered moving there in 1990 and 2015.  But it's just too damned hot.  
  • Oklahoma.  I am one of those rare people that like Oklahoma and Texas, so I don't get caught up in that rivalry, especially since I don't care for football.  My first wife (RIP) was born in northwestern Oklahoma and during our numerous family trips through the area, there wasn't time for numerous geology and photography stops.
  • Georgia Piedmont.  My home territory.  I have lived there for 52 of my 66 years.  My "Undergrad Thesis" was done there, related to the Lithonia Gneiss and Triassic Diabase Dikes.
  • Georgia Coastal Plain.  I earned my Bachelor's Degree at Georgia Southern College (now University), received my two Photography courses there, and later worked there for 8 years (1992 -2000).  Most of my publications are related to the Georgia Coastal Plain and Middle and Late Eocene fossils
  • Bisti Badlands, San Juan County, New Mexico.  I had a great Summer Job during a Fossil Recovery Project in 1979.  (I got paid to find dinosaur bones!  At certain ages, that is a good way to get a kid's attention and perhaps distract them from boredom.)
  • New Mexico.  Aside from my Summer Job in San Juan County, I have had exposure to many of the Volcanic Fields in New Mexico, except for a few missing spots, e.g., the Mount Taylor Volcanic Field, and some of the volcanic centers related to "The Great Ignimbrite Flareup".  [One of my Geo-Bucket List items was to visit the Clayton-Raton Volcanic Field in northeast New Mexico.  I did that during my 2015 Arizona Trip #2.]  I wanted to revisit White Sands during my 2015 and 2016 trips but just didn't have the time. 
  • Arizona.  (For the family reasons mentioned earlier.)  And the glorious things I have seen.  Seeing Sunset Crater was a Bucket List item that I achieved in 2015.  I would like to see more of the San Franciso Volcanic Field.  I also saw my first Dinosaur Tracks near Tuba City and visited Monument Valley in 2015.
  • Nature Photography.  My major influences responsible for my love of Photography were my Dad and one of my most influential professors at Georgia Southern.  During my 1974 Road Trip, I hadn't yet taken any Photography courses and I didn't think to borrow my Dad's Minolta SRT-101 35 mm camera.
  • Texas.  (I lived there from 1977-1991, in El Paso.  Traversed the state many times during and after.)  Got married the first time there in 1984 and adopted our first baby there in 1986.  Our second adopted baby was born in San Antonio in 1994.  I wish I had taken the time to visit the Big Bend area and the Davis Mountains while I lived in El Paso.  And I wish that I could have done more fossil collecting in the Edwards Plateau limestones
  • Ecology.  Including aspects of Flora and Faunas, as well as relationships to Weather & Climate.
  • Bucket List items.  Including a few accomplished in the last 10 years, as an encouragement to others to do the same (and write about it too!).
  • Road Food.  Some local culinary discoveries.
  • Hobbies and Avocations.  Includes the requisite Rock, Mineral, and Fossil Collecting, as well as continuing learning about local Flora and Fauna; engaging in local roadside and creekside trash pickups (since the first Earth Day in 1970); and Beer Can Collecting (since 1974).  I have met several fellow Geologists in this hobby.
  • Writing Projects.  Since turning 60 in 2014, I have had a "hankering" to "tell my story" or at least parts of it, in case my kids ever want to know the events leading to my moving to El Paso in 1977 and meeting their Mom in 1983.  I want to at least produce a spiral-bound narrative to leave behind when my time is up.  Blogging is one of the ways I keep in practice, until "my mojo" returns.  (It seemed to go away after my second wife's car accident in September 2019.)

There may be more to come, including some links and perhaps a few photos.

The Chihuahuan Desert: Our North American Outback

 

[This video was previously posted on November 30, 2019.  The Chihuahuan Desert was my home for 14 years and remains influential to my thoughts of Geology and Ecology.]

As I was searching through videos related to the Chihuahuan Desert, I encountered a familiar name.  Kevin von Finger was a casual friend of mine during my El Paso years, we crossed paths often.  (I wish I had spent more time rambling in the desert with him.  He passed away too young.)  

As our personal encounters were usually during social events, I wasn't properly aware of his career as a local Ecologist and Biologist.  (To my great regrets.)  At that particular time, my primary life focus was Geology, but for the most part, my self-education in Ecology and Environmental Science had not begun in earnest.
