Location and accuracy | This is a lode prospect on the west slope of Spruce Creek valley; it is at an elevation of about 450 feet, 1.2 miles upstream from the mouth of Spruce Creek on the Casadepaga River. It is locality 10 of Cobb (1972, MF 445; 1978, OF 78-181). |
Geologic descriptionA zone of silicified rock, possibly replaced marble, near a contact with schist contains copper sulfides and carbonates (Smith, 1908; also see Mount Dixon, SO068). Bedrock in Spruce Creek is primarily part of a lower Paleozoic metasedimentary assemblage (Till and others, 1986). | |
