Mono Basin and Hot Creek Area

Panum Crater (left) with the Mono Craters in the background (left & center) on the dirt Old RR Grade. The Mono Basin is an area where much of the deformation between the North American Plate and the Pacific Plate occurs. Long before the Sierras and Mono Basin existed, the area subsided from crustal stretching along with volcanism and faulting. The area remains volcanically active today, with Paoha Island forming from volcanic activity 350 years ago. Trip to the South Tufa Area of Mono Lake.
