Yesterday I led a field trip to the Wichita Mountains Wildlife Refuge for a nature hike. For many of them this was their first trip to the WMWR and I believe everyone enjoyed it. Here are some photos I snapped that don't include faces.

Nice pics.
Interesting that the outcrops look to have been eroded by glaciers at some point (rounded and scoured like that). I didn’t realize they had extended that far south in the last ice age. Maybe previously…?

The Wichitas granite formed around 500 million years old by the Southern Oklahoma Aulacogen. The mountains themselves were formed around 350 million years ago during the approach of the the South American and North American plates, where I live this culminated with the Ouachita Orogeny (which stretches from south central Texas through Mississippi) some 325 million years ago. What we see today in the Wichitas is not glacial erosion but just some 350 million year's worth of erosion. One interesting bit of trivia is that the Southern Oklahoma Aulacogen is also responsible for the Anadarko Basin which is one of the deepest basins in the world. At its deepest it has some 40,000 feet of sedimentary rock, and it is unusually rich in natural gas and oil.
 
Thanks for that! I have worked in OK doing seismic exploration but the closest I ever got to the Wichita Mountains was Lawton. This was many years ago, probably before BCF was a gleam in Basil’s eye…
I could see them in the distance occasionally but most my work was up towards OKC, Enid/Alva area, and a bit towards Tulsa if I remember correctly…
 
That looks like a very cool place. Do they have any sort of camping anywhere nearby?
 
They have a camp ground on the refuge, Camp Doris.
 
Nope.
