Location and accuracy Edgar Creek is a west headwater tributary of the Kuyukutuk River. The prospect is on the north side of the headwaters of Edgar Creek and is approximately located, perhaps within one-half mile. The map site is at an elevation of 750 feet, in the SW1/4 sec. 20, T. 21 N., R. 68 W., of the Seward Meridian. This is locality 2 of Hoare and Cobb (1972, 1977).

Geologic setting

Geologic description

Harrington (1918) reported that free-milling gold in quartz veins was discovered near the head of Edgar Creek. Claims were staked on these veins, but other information about them is not available. Hoare and Coonrad (1959) show a prospect symbol at this location and interpret the country rocks as Paleozoic to Mesozoic sedimentary and volcanic strata of the Gemuk Group.
