|Location and accuracy||Adams Creek is the main headwater tributary to Shovel Creek (SO017). Very little mining is reported for this creek and the location of workings is uncertain; probably within 1.5 miles of the coordinates. This is locality 88 of Cobb (1972, MF 445; 1978, OF 78-181).|
Geologic descriptionGold was discovered early on Adams Creek and small-scale mining produced 50 to 60 ounces on one claim in 20 days (Brooks and others, 1901). The stream gravels are 4 to 6 feet thick and heavy mineral concentrate contains garnet and magnetite. The active drainage is incised 5 feet into an alluvial terrace. Bedrock in the area is mostly part of a metavolcanic assemblage thought to be Ordovician in age (Till and others, 1986).
