|Location and accuracy||Willow Creek is a south tributary to Pilgrim River. The mouth of Willow Creek is 4.7 miles downstream from the head of Pilgrim River on Salmon Lake. It is the next south tributary to the Pilgram downstream from Slate Creek (SO138); it is not identified by name on the Solomon D-6 quadrangle. This is locality 26 of Cobb (1972, MF 445; 1978, OF 78-181).|
Geologic descriptionThere was some small scale placer mining on this creek prior to 1909 (Collier and others, 1908). The lower part of the creek flows through bench gravels (Brooks and others, 1901) and some bench gravels between Slate Creek (SO138) and Willow Creek are reported to be gold-bearing (Collier and others, 1908). Bedrock in the area is mostly part of a lower Paleozoic metasedimentary assemblage (Till and others, 1986).
