The Place

Mount Diablo

Two major Bay Area faults, the Las Trampas and Bollinger faults, run through this park and account for the uplift of the steep ridges with deep canyons between. These tectonic forces have also caused the exposure of well-defined geological formations. One formation holds remnants of ancient beach and shoreline, another consists of several fossil-bearing compressed rock layers and another is of volcanic origin.

Turn left on Corduroy Hills Trail which takes us over Eagle Peak and down to Madrone Trail. We turn left and follow it up to our meeting spot on Las Trampas Peak. We return following the Las Trampas Ridge/Calaveras Ridge Trail to the Chamise Trail.
