A thin auriferous quartz vein strikes N 30 W, and dips 60 W. Rich float (presumably, in gold) reported just below the outcrop.
Workings: Limited surface work reported in the summer of 1931 (Park, 1933).
Age: Tertiary or younger; veins cut both Late Cretaceous Valdez Group rocks and Teriary intrusive rocks.
Alteration: The intrusive rocks have undergone argillic alteration.
Commodities (Major) - Au
Development Status: Undetermined
Deposit Model: Chugach-type low-sulfide Au-quartz veins (Bliss, 1992; model 36a.1)
