Description :
Sand ramps are amalgamated accumulations of aeolian, fluvial, and talus deposits. They have developed as a result of the interaction of wind blown-sand and desert piedmont processes adjacent to mountain ranges in the Mojave Desert and occur next to regional and local sand transport corridors. Periods of geomorphic stability are represented by paleosols and talus accumulations. The sand ramps provide a record of the response of aeolian processes to climatic change in the Mojave Desert. Most are now relict features and accumulated in periods of higher sediment supply from fluctuating and/or desiccating paleolakes during the late Pleistocene.
