2011 Foresta Road debris slide

A debris slide from a steep slope above forms a cone of rock and soil material that is covering both lanes of a road. Three people stand by the slide observing.

A debris slide occurred onto Foresta Road between Rancheria and El Portal, just west of the El Portal wood lot. The slide initiated from a tall road cut and consisted of soil and angular metamorphic clasts on top of weathered granitic bedrock. The cone of slide material covered both lanes of Foresta Road, up to 6-7 m deep on the northern (westbound) lane.
