On the way to Black Mesa, Oklahoma, I stopped to check out this fantastically preserved cinder cone volcano in the desert. This is in a lava field with dozens (hundreds?) of other volcanic features. A road circles the cone and ends up at the base of the crater. A hiking trail circles the rim and was a great hike for Teewinot and I. We soon got back in the A/C and headed to Oklahoma.
Clearly some good volcanic soil!
