Mount Diablo is a mountain in Contra Costa County, California in the San Francisco Bay Area, located south of Clayton and northeast of Danville. It is an isolated upthrust peak of 3,864 feet (1,178 m), visible from most of the San Francisco Bay Area and much of northern California.
Mount Diablo is sacred to many California Native American peoples; according to Miwok mythology and Ohlone mythology, it was the point of creation. Prior to European entry, the creation narrative varied among surrounding local groups. In one surviving narrative fragment, Mount Diablo and Reed’s Peak [Mt. Tamalpais] were surrounded by water; from these two islands the creator Coyote and his assistant Eagle-man made Indian people and the world. In another, Molok the Condor brought forth his grandson Wek-Wek the Falcon Hero, from within the mountain.
