EARTHQUAKE FAULT (Mammoth Region, Eastern Sierras, Mono County, CA)

An interesting detour off of Hwy. 203 en route to Mammoth Lakes. By all accounts, this split (10' wide x 6' deep) in the earth's crust is more of a fissure than a fault and, although undated, is probably on the young side (at least 160 years old based on the trees growing in the fissure, per the USFS' website) and associated with the Inyo-Mono craters fault system.

9/7/02 Earthquake Fault.

9/7/02 There's an easy dirt trail from the parking area with guard rails, from which you can peer down into the fissure.
