Geologic setting

Geologic description

An unpublished National Park Service map and accompanying database identify this as a placer gold prospect where one claim was active from 1916 to as recently as 1963. It is in the headwaters of Pensive Pup, a small headwater tributary to Little Eldorado Creek. Pensive Pup reworks Quaternary colluvial and glacial deposits downslope from exposures of Jurassic marine siliciclastic rocks (Richter and Jones, 1973). Some of the glacial deposits may have been derived from the Gold Hill area to the south, where the mid-Cretaceous, Chisana pluton intrudes Cretaceous volcanic and volcaniclastic rocks (Richter and Jones, 1973). This placer is one of several developed within or peripheral to the Chisana pluton (Richter and Jones, 1973; Richter and others, 1975).
