|Location and accuracy||There is little information about placer mining along Canyon Creek but Kurtak and others (2002) reported mining in 2000 'near the narrows'. That feature is probably about 1.3 miles upstream from the mouth of Canyon Creek where the creek cuts through a low ridge. This location is about 0.5 mile north of the center of section 17, 32 N. R. 7 W.|
Geologic descriptionIn his detailed list of the placer deposits of the Koyukuk area, Reed (1938) found no evidence of mining or prospecting on Canyon Creek. Kurtak and others (2002) reported claim staking in 1978 and 1982-1983, and mining in 1986 and 2000.
