|Location and accuracy||Bear Gulch is a very small north tributary to Minnesota Creek; it is located about 1.5 miles upstream of the confluence of Minnesota Creek and Penny Creek (SO018) and about 2.3 miles north of Quigleys Camp on the Solomon River. The lower part of Bear Gulch is at an elevation of 350 feet. This is locality 92 of Cobb (1972, MF 445; 1978, OF 78-181).|
Geologic descriptionSmith (1910) reports that most of the gravels in this drainage were mined by 1907. Bedrock is part of a lower Paleozoic metasedimentary assemblage (Sainsbury and others, 1972, OFR 511; Till and others, 1986).
