Strataday

Lynch, D. “Encore,” Folding and Faulting. Calico Mountains, California.

Studying and mapping the recently discovered Twin Lakes Fault on Mount Hood, Oregon. This segment bounds Frog Lake, and the lake is being dropped down while the mountain is being uplifted. This is called a normal fault. In most places, the scarp is about 1.5m high. The downed tree crosses the scarp.
