Geologic setting

Geologic description

A pan-concentrate sample of stream gravels at this site contained chromite, gold, ilmenite, magnetite, olivine, scheelite, sphalerite, and zircon (Rose and Saunders, 1965, p. 15). The source of some of these minerals may be glacial till and possibly granite that has been reported in this vicinity (Rose and Saunders, 1965).
