|Location and accuracy||This alluvial gold placer mine is on Grouse Gulch, a small north tributary to Dexter Creek (NM303). The map location is at an elevation of about 400 feet in the NE1/4 section 31, T. 10 S., R. 33 W., Kateel River Meridian. Grouse Gulch is included in locality 118 of Cobb (1972 [MF 463], 1978 [OFR 78-93]).|
Geologic descriptionGrouse Gulch heads on the divide between Dexter Creek (NM303) and upper Anvil Creek (NM236). It is one of several small headwater tributaries of Dexter Creek that head in areas where high-level auriferous gravels have been mined (for example, NM246). Placer gold mining in these tributaries took place before 1908, and some of the deposits were very rich; a 3-ounce nugget was recovered from Grouse Gulch (Brooks and others, 1901; Collier and others, 1908). Much of the placer gold in the headwaters of Dexter Creek, including the gold in Grouse Gulch, is probably derived from reworking the high-level gravels.
