For Those Dropping By ...
Being somewhat "trapped indoors" this year by the pandemic - aside from normal routine responsibilities - I have had an inordinate amount of time to think about my geologic past and what I might want to do if future opportunities present themselves. Perhaps an informal Bucket List (or Geo-Bucket List), if you will. (I have blogged about this more-than-once.)
One of my major goals is to revisit The Crater of Diamonds State Park near Murfreesboro, Arkansas one more time (hopefully during cool weather). I found a 37-point (.37 carat) "white" (clear) diamond on my first visit in 1973 (but lost it during 2011 home renovations). Subsequent visits were made in 1978, 1984, and 2015 with no such luck. While there in spring 1978, a couple from Dallas, Texas screening gravel near us found a brown 4-carat diamond and I got to hold it.
For those unfamiliar with the place, it is the ONLY operating diamond mine open to the public worldwide. (Think about that.) After you pay your $10 entrance fee, you can keep anything you find. Anything. That being said, there are no guarantees about finding anything, but if you do some advance preparation, it might increase your chances.
Here is a partial list of short videos and my blatherings about Diamonds and how to find them, with additional videos being posted (usually one per day, except for October 14, 2020, when I posted a flurry of 11 videos) as I found them on YouTube.
Other repeat and random posts are on the subjects of Gold (as several ancestors were involved in the 19th century Georgia and California Gold Rushes), travels on U.S. Hwy 66 (aka Route 66), the Chihuahuan Desert (where I lived while in El Paso from 1977 - 1991), and the U.S. travel writer William Least Heat-Moon. So my primary goals are to entertain and inform.

Another Important Scientific Principle - Multiple Working Hypotheses
More than once I have gained tentative permission for a preliminary visit to a site. Once the "home office", the absentee land-owner, or corporate lawyers are notified, the "green light" changes to "yellow", or worse, "red". At one site, in 1999, the Coastal Plain property was a quail-hunting preserve, and the land custodian said "fine" for us to do a preliminary visit to check out the lithologies and Middle Eocene fossils present. [It wasn't quail season, anyway.]
Ruling Theory: The "method of the ruling theory" begins with a ready answer to which the thinker grows attached, looking only for facts that confirm the answer. [Which introduces "Confirmation Bias", a normal human practice.]
Working Hypothesis: The "method of the working hypothesis" begins with a tentative answer, the hypothesis, and seeks out facts to try against it. This is the textbook version of science ... Plate tectonics is a healthy working hypothesis, being extended today in full awareness of its uncertainties.
Multiple Working Hypotheses: The method of multiple working hypotheses begins with many tentative answers and the expectation that no single answer may be the whole story. Indeed, in geology, a story is what we seek, not just a conclusion ...
Discovering the true story means weighing and combining different working hypotheses. Charles Darwin, 40 years earlier, had done just this in devising his theory of species evolution.
The scientific method of geologists is to collect information, stare at it, try a lot of different assumptions, read and discuss other people's papers and grope their way toward greater certainty, or at least figure the answers with the best odds. This is more like the real problems of real-life where much is unknown and variable—planning an investment portfolio, devising regulations, teaching students.
The method of multiple working hypotheses deserves to be more widely known. In his 1890 paper Chamberlin said, "I am confident, therefore, that general application of this method to the affairs of social and civic life would go far to remove those misunderstandings, misjudgments, and misrepresentations which constitute so pervasive an evil in our social and our political atmospheres, the source of immeasurable suffering to the best and most sensitive souls."
Chamberlin's method is still a staple of geological research, at least in the mindset that we should always look for better answers and avoid falling in love with one beautiful idea ..."

My 2015 and 2016 Encounters With U.S. Hwy. 66 - Part 2
When I returned home at the conclusion of "2015 Arizona Trip #1", I was glad to be there, but still struck by the sudden, awesome (overwhelming) silence of an almost "empty nest", I decided that I had to get out again. My daughter was married and living in Phoenix, my son was working, and my wife was gone. I needed to get out and go west again.
This time was a chance to visit some long-bypassed Geology stops, to stop and take photos any time I pleased, maybe take in two or more Bucket List items, and to engage in much needed "driving and crying".
In 2009, I had planned on visiting the Clayton-Raton Volcanic Field during our summer vacation, but last-minute changes nixed that plan, so that was "on the list", as was Palo Duro Canyon, south of Amarillo, necessitating the taking of I-40 on the westward leg of the journey. Within the westward I-40 corridor, Route 66 "joined" in Oklahoma City.
Despite the late start, I made the 300 miles to Tupelo that first day. I made plans to leave out early the next day and get as far past Oklahoma City as I could. Other than gas stops and perhaps one beer stop, the only "must-do" stop was a local burger place in Russellville, Arkansas.
When I rolled into the Best Western Inn in Weatherford, about 45 minutes before sundown, I had covered 650 miles that day. "Not bad for an old guy", but I was too worn out to go any further. The 525 Main Street address was part of Route 66. Tomorrow was to be my first day of "seeing some stuff" (primarily Palo Duro Canyon State Park).

Oklahoma Rocks Part 1
My 2015 and 2016 Encounters With U.S. Hwy. 66 - Part 1
An interesting take on Route 66.
As my daughter needed her SUV, we (including the dog) had to get to Phoenix, by way of I-20 and I-10, ASAP. We made it in just over 2 and 1/2 days. Once in Phoenix, we stayed for about a week. As I hadn't been out west in a few years, Neal and I visited a number of local breweries in Phoenix and Flagstaff (and others on the way back to Georgia). We made a one-day foray into Flagstaff for a "beer run" of sorts as we planned to cruise through Flagstaff a few days later, before the beer stores opened.
As we left Oklahoma City the next day (being on the road was wearing us down), as we were planning the final days of our trip along I-40, while driving, we were leaving U.S. 66 behind. (As recounted, U.S. Hwy. 66 had not been a major side interest.)
Amidst the hurried planning for the "2015 Arizona Trip #2", I hadn't immediately thought of The Big Texan. That turned out to be a "spur of the moment" decision when I reached Amarillo on the 3rd Day of Trip #2. [To be continued ...]

A Review of Bucket List (Geo-Bucket List) Completions
In this March 2015 post, I included a number of geological-places-of-interest, with the lower-48 states that I would like to visit or revisit, if personal responsibilities, time, and budget realities allow. (I am primarily doing this post to include photos from most of those "completed" list items.)
Perhaps stated in "elsewhere writings" (or in future pontifications), having an informal or formal "Bucket List" can be a "vessel" for personal inspiration, especially after completing the first few items. (As self-doubt is a major impediment to personal improvements, almost any positive motivation is good.)
Yeah, it's a little bit of "sour grapes", but it is also a warning to others to have a "five-year plan", i.e., an escape route due to the propensity of certain institutions to "use and discard" adjuncts. (I am certainly not alone. And not having that five-year plan is certainly my naive fault.) But, so it goes.
In the aftermath of Spring 2015 personal tumult and family changes, I managed to make three driving roundtrips between Atlanta and Phoenix, two in the summer of 2015 and one in the summer of 2016.
A significant number of these were things I had "missed" during previous travels and field trips due to not having a decent camera particularly in 1973 and 1974, camera malfunctions in 1977 and 1979, screwups in 1982 travels, or not being able to stop during family trips.
So, in no particular order, here are the personal successes of the 2015/2016 travels (the original explanations of reasons and intentions are in the March 2015 post):
Monument Valley, AZ/UT.
Clayton-Raton Volcanic Field, NE New Mexico.
(Visited during 2015 Arizona trip #2.) Originally planned as an extension of a 2010 family vacation, but changes had to be made in the schedule.
Sunset Crater, Flagstaff, AZ area. Despite having visited the Grand Canyon in 1973, 1974, 1978, and several times after the year 2000, to my regret, I didn't visit Sunset Crater. I took care of that during 2015 Arizona Trips #1 and #2.
Though climbing the slopes of the large cinder cone is strictly forbidden (because of erosion concerns), there is plenty to see around the base of the 900-year-old volcano.
(Reminder, these are in no particular order.)
Palo Duro Canyon, Texas.
Arches National Park, Moab, UT area.
Because of camera glitches on two previous trips to Arches National Park (1977 and 1979), leaving me with zero photos, I had to try one more time. On the way from my previous night's stay in Beaver, Utah, I made numerous geo-photo stops primarily along I-70 that morning, getting me to the Park midday, hoping "the third time would be the charm" (it was).
Vicksburg, MS loess. Just to touch it, just to feel it and its texture.
Addendum:
(Things I forgot to add.)
Monahans Sandhills
Dinosaur Tracks (in no particular location)
