Alluvial fan and catchment initiation by rock avalanching, Owens Valley, California

Authors(s) and Affiliation(s)



The North Long John alluvial fan of the Inyo Mountains piedmont, Owens Valley, was catastrophically initiated by a prehistoric (early Holocene?) rock avalanche. The key implication of this study is that not all fans of a particular piedmont are of the same longetivity or stage of development. This study also points out that the geological hazards on the piedmont beneath triangular bedrock facets (rockfalls, roskslides, and rock avalanches) contrast with the dominantly debris flow or water-flow hazards of the more mature fans. This study demonstrates that complications arise from differences in the timing of fan inititation, and with the degree of diachroneity
