Abstract

The highly visible erosional scars near the crest of the San Bernardino Mountains just east of Strawberry Peak near the community of Rimforest are active landslides. From at least the 1920's to 1988 the primary activity has been mass wasting by rockfall in highly fractured quartz monzonite. Tension cracks in the adjacent area indicate that active landsliding may be spreading. Landsliding in this area had its origin most likely with the uplift of the San Bernardino Mountains and has continued with periods of active movement associated with heavy precipitation and seismic activity separated by long periods of dormancy. The geomorphology of the area suggests that the currently active landsliding may be only a small part of a large ancient landslide.
