Description
The author examined the fluvial geomorphology of the Amargosa River, located in Death Valley, California (~35.75N, 116.25W), in an attempt to reconstruct a Holocene history of the hydroclimatology of the region. Results indicated that two major aggradational periods, likely associated with wetter climates, were separated by a substantial erosional period that occurred between ~ AD 800 and 1400, which was likely the product of an era of low-frequency, high-magnitude floods that occurred during an overall drier climatic regime associated with the Medieval Warm Period.
