|Location and accuracy||This prospect is located on the east flank of Willow Mountain, about one-half mile west of the Richardson Highway; it is at an elevation of about 3,000 feet in the northeast corner of section 22, T. 1 S., R. 1 E., of the Copper River Meridian. This prospect is approximately located, perhaps within one-quarter mile. It is locality 53 of Cobb and Matson (1972) and locality 44 of Winkler and others (1981 [OFR 80-892-B]).|
Geologic descriptionHydrozincite and smaller amounts of chalcopyrite and malachite are sparsely but widely disrtibuted in limestone of the Jurassic Talkeetna Formation (Berg and Cobb, 1967, p. 52; Winkler and others, 1981 [OFR 80-892-B]; Winkler and others, 1981 [OFR 80-892-A]).
