|Location and accuracy||This placer occurrence is about 1.5 miles west of the village of Chekok, apparently on a distributary of Canyon Creek. The site is in the NW1/4 section 25, T. 4 S., R. 30 W., Seward Meridian. The location is accurate within 0.5 mile. The occurrence is locality 35 of MacKevett and Holloway (1977).|
Geologic descriptionThis placer gold occurrence is on an unnamed distributary of Canyon Creek, which drains the north and west flanks of Knutson Mountain. The site was covered by placer gold claims, but little is known of the occurrence (U.S. Bureau of Mines, 1973). The bedrocks in the stream drainage comprise Tertiary and Jurassic volcanic rocks and Mesozoic plutonic rocks (Detterman and Reed, 1980). The nearest known lode deposit is the Knutson (IL011) which is about 3.5 miles northeast of the placer claims.
