Geologic information

Identification information

Deposit ID 10307325
Record type Site
Current site name Sawlog Creek

Geographic coordinates

Geographic coordinates: -149.1533, 67.39971 (WGS84)
Relative position Sawlog Creek is a small headwater tributary to the South Fork Koyukuk River. The mine site (as shown in Brosgi and Reiser, 1964) is approximately 3 miles southeast of South Fork Lake and about 1 mile upstream from where Sawlog Creek enters the valley of the South Fork Flats (sec. 29, T. 30 N., R. 7 W., of the Fairbanks Meridian). It is just north of the low pass that separates Sawlog Creek from Dennys Gulch. The location is accurate within a 1/2-mile radius.

Comments on the geologic information

  • Geologic Description = Brosgi and Reiser (1964) reported recent placer mining in 1964, but there is no other information regarding this placer occurrence. The area is mapped as quartz-mica schist with intercalated greenschist and greenstone. Sawlog Creek heads against Dennys Gulch (CH019), in which there is documented placer activity, and both creeks are just south of the southern end of the Baby Creek batholith (DeYoung, 1978).
  • Age = Quaternary.

Economic information about the deposit and operations

Development status Past Producer

Comments on exploration

  • Status = Not determined

Mining district

District name Koyukuk

Comments on the workings information

  • Workings / Exploration = Williams (1952) reported that the results of a magnetometer survey on Sawlog Creek looking for a pay streak were generally inconclusive, but because the survey was performed at the request of the property owners it suggests some activity at that time. Heiner and Wolff (1968) reported one claim located in 1960.
