Geologic setting

Geologic description

Bedrock in the drainage is a slaty metapelitic and metasandstone sequence of unknown but probable Paleozoic age locally intruded by altered mafic bodies (Sainsbury, 1972). The one USBM churn-drill hole completed at this location encountered 15 feet of gravel above bedrock. Heavy mineral concentrates from this drill hole contained a trace of tin and gold. The heavy minerals included garnet, limonite psuedomorphs after pyrite, pyrite, ilmentite, magnetite, augite, tourmaline, hornblende, zircon, epidote, sphene, hypersthene, staurolite, cassiterite, and gold.
