Photograph of south wall of the trench across the small scarp at Rito Seco showing the Santa Fe Formation (QTsf) and the boulder-cobble gravel (Qg) and debris flow (Qdf) on both sides of the fault. The colluvial wedge (Qcw) is the sediment that was eroded from the scarp that formed after the most recent large earthquake at this site. Younger deposits on top of the colluvial wedge are sediment that has washed down the slope.
