Prior to starting our volunteer time at Big Bend National Park we had the pleasure of having a field day with Don, the park Geologist, introducing us to the geology of Big Bend (thank you Don).
Considered as a paradise for Geologist, some scientist disagree and look at this area of twisted and tortured rocks as a "Geologists Nightmare".
From 500 hundred billion year old rocks at Persimmon Gap to modern day windblown sand dunes at Boquillas Canyon, Big Bend shows a wide variety of depositional styles.
The images may only give you a reduced picture of the rocks that make this stretch of land "rock".
Most of all, Big Bend National Park allows us to reflect about the beauty of nature and how we are an integral part of it: "Rocks and waters, etc., are words of God, and so are men. We all flow from one fountain soul. All are expressions of one love" (John Muir).
