About Me

My photo
on-the-rocks
As a Geologist/Naturalist with a strong interest in Photography (and being an aspiring writer), I hope to use my travels in the continental U.S. and my experiences (and mistakes) as Educational Resources. I have a constant "yearning to learn" and a desire to better understand the things that I see and have seen in the past. I grew up on the Georgia Piedmont, received my B.S. in Geology and later worked on the Coastal Plain, and spent 14 years in El Paso, where I received my Master's Degree and learned much about the Chihuahuan Desert.
