Location: This occurrence is along the range front on the north side of Death Valley. It is on the north side of an unnamed north tributary to Tubutulik River where it enters Death Valley from its headwater uplands. This occurrence is 3.7 miles northwest of Camp Haven (northeast Death Valley). It is locality 40 of Gamble (1988).
Geology: A cold spring comes to the surface at this locality and a grab sample of surface material here contained greater than 10,000 ppm bismuth (Miller and Grybeck, 1973). This location is close to an inferred range front normal fault with probable Quaternary displacement. However, an alluvial fan is developed where the nearby stream enters onto the lowland of Death Valley and the surface trace for the inferred fault is not apparent.
Workings: None.
Age: Quaternary
Commodities (Major) - Bi
Development Status: None
Deposit Model: Surface precipitates from a cold spring contain Bi
