|Location and accuracy||Tiny Gulch is a small tributary on the south side of lower Bear Creek. It is about 0.8 mile upstream of the mouth of Bear Creek on the Tuluksak River. The map site is on lower Tiny Gulch, in the SE1/4 sec. 27, T. 11 N., R. 60 W., of the Seward Meridian. It is locality 18 of Hoare and Cobb (1972, 1977).|
Geologic descriptionTiny Gulch cuts through alluvial bench deposits on the south side of Bear Creek (RM032). From 1909 to 1914, placer mining of 2- to 3-foot-thick gravels on the lower part of the creek produced about 250 ounces of gold (Maddren, 1915).
