Geographic coordinates

Geographic coordinates: -164.32644, 65.53822 (WGS84)
Relative position Boulder Creek is a north tributary of the Noxapaga River. Placer mining has occurred along the main drainage of Boulder Creek at a location slightly over a mile upstream of its juncture with the west tributary, Turner Creek. This is 1.4 miles downstream of the mouth of Goodall Creek, a smaller west tributary to Boulder Creek. This is locality 47 of Cobb (1872; MF 417; 1975; OFR 75-429).

Comments on the geologic information

  • Geologic Description = Gold was discovered on Boulder Creek in 1901 and initial mining encountered 2.5 feet of muck and 4 to 5 feet of unfrozen gold-bearing gravel over frozen gravel (Collier and others, 1908). Some gold was coarse and rounded; a 2-ounce nugget was recovered. The gold-bearing character of the deeper, frozen gravel was not determined by early work. A 11 foot-deep prospect pit, 1.75 miles upstream of the mouth, did not reach bedrock. Bedrock in the area is extensively covered by tundra (Till and others, 1986) but Collier and others (1908) indicate that it includes calcareous schist, limestone (marble), and minor graphitic schist. These lithologies are present regionally in a Lower Paleozoic metasedimentary assemblage (Till and others, 1986).
