Geomorphology of the East Flank of the Spring Mountains, Nevada.

Abstract

The eastern flank of the Spring Mountains, Nevada exhibits pedimented alluvial fans derived from canyons trenching the mountains. The alluvial and colluvial fill of the canyons is undergoing excavation which exhibit at least two major standstill periods. The periods of standstill evidenced by terraces in the canyons also resulted in pedimentation of the fan surfaces and the terraces can be traced onto the fans as partially preserved pediments. The bedrock of the Spring Mountains is dominantly carbonate and extensive calichification and case-hardening has developed on the alluvial and colluvial material in the canyons and on the fans. These cementation processes are extremely rapid, developing within one year. Color aerial photography, and to a lesser extent color IR photography, allows mapping of the fan surfaces and establishment of crude estimates of cementation. (Author)
