|Location and accuracy||The coordinates are the approximate center of placered ground on Bedrock Creek, in the NW1/4NW1/4 sec. 30, T. 3 N., R. 2 E., of the Fairbanks Meridian. The location is accurate.|
Geologic descriptionAs least some placer mining was done on Bedrock Creek as can be seen by the gravels there but details are lacking. Some placer gold was probably produced; cassiterite is common, but scheelite is scarce (Joesting, 1942; ATDM Pamphlet. 1, p. 32).
