|Location and accuracy||Butte Creek is a west tributary to the Solomon River. The mouth of Butte Creek is 2 miles upstream of East Fork. Mining took place over the lower 0.3 miles of Butte Creek and about 0.5 miles of the South Fork tributary of Butte Creek. This is locality 95 of Cobb (1972, MF 445; 1978, OF 78-181).|
Geologic descriptionThe gravels in lower part of creek were thoroughly worked prior to 1907 (Smith, 1910). Bench gravels on the west side of South Fork were productive. The bench gravels were about 8 feet thick on schist bedrock; the surface of the bench was 20 to 25 feet above the active channel. The part of Butte Creek that was mined follows a contact between schist and marble within a lower Paleozoic metasedimentary assemblage (Till and others, 1986).
