Las Trampas Peak

Las Trampas Peak is a one thousand eight hundred twenty-seven-foot mountain in western Contra Costa County, California, at the end of Las Trampas Ridge in the Berkeley Hills. Its Spanish name, meaning “the traps,” reflects the Saclan Bay Miwok peoples’ use of steep canyons to funnel and hunt elk and other game, preserving an older human connection to the landscape. The peak is formed largely of Miocene marine sedimentary rock, including fossil-bearing layers that show these hills were once part of an ancient marine environment. As the source of Las Trampas and Grizzly creeks, and within Las Trampas Regional Wilderness, it also anchors a protected landscape of varied habitats and wildlife.
