Landslide deposits, undifferentiated
Landslide deposits, undifferentiated
Holocene to Pliocene
Unconsolidated to moderately consolidated mass wasting deposits of variable thickness. Composition and internal texture are highly variable and dependent upon source rock unit(s). Not differentiated by age; predominantly later Pleistocene to Holocene but includes earlier Pleistocene to Pliocene deposits. Spatial distribution reflects both relative landslide susceptibility of source rock units and variability in landslide mapping in source maps. Includes both individual failures and landslide complexes depicted as single polygons. Mega-landslides occur in the eastern Sierra and are depicted separately with overlay polygons to preserve compiled geologic mapping and with consideration to the uncertainty of some interpreted mega-landslides.
