|Location and accuracy||This prospect is in the headwaters of Pensive Pup, a small headwater tributary to Little Eldorado Creek. It is at an elevation of about 5,500 feet, about 1 mile northeast of the small pond at Caribou Pass. The prospect is near the southeast corner of the NE1/4 of section 13, T. 4 N., R. 19 E. of the Copper River Meridian. This is National Park Service locality WRST-63 (unpublished data) and the coordinates for this prospect were provided by the National Park Service.|
Geologic descriptionAn unpublished National Park Service map and accompanying database identify this as a placer gold prospect where one claim was active from 1916 to as recently as 1963.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).
