Geologic setting

Geologic description

The only information is that two lode claims were staked in granite porphyry (U.S. Bureau of Mines, 1973). The granite porphyry has phenocrysts of quartz, plagioclase, and potassic feldspar up to 4 mm across in a groundmass of quartz, potassic feldspar, and plagioclase grains up to 1 mm across (Nelson and others, 1983; unit TKi10).
