One of our favorite River Road companions

The teepees on the River Road, Hwy 170 between Presidio and Terlingua

One of the most scenic drives in the state is Hwy 170, from Presidio to Terlingua/Study Butte, and if you're a geology buff, one of the best ways to explore the road is with William MacLeod's River Road Vistas.  Mile by mile, the text, photos and diagrams tell how the landscape formed, by volcanic action, erosion and other factors.
