Landslide near Pacheco Pass, Pacheco State Park, Merced County, California

Slump on a grassy hillside
A slump in Pacheco State Park in the Diablo Range in western Merced County. This slump formed in deeply weather bedrock consisting of serpentinite (the State rock of California). A small stream (located near the trees in this image) had undercut the slope, helping to initiate the ground failure. Note the arc-shape scarp at the top of the slump and the lumpy and fractured surface of the slump itself.
