Location: Rocky Creek is a southeast tributary of California Creek in the headwaters of the Tuluksak River. Most of Rocky Creek has been placer mined upstream from its confluence with California Creek. The map site is the approximate midpoint of the placer workings. It is near the center of sec. 11, T. 11 N., R. 60 W., of the Seward Meridian. Rocky Creek is included in locality 17 of Hoare and Cobb (1972, 1977).
Geology: The placer deposit on Rocky Creek is a continuation of the deposit on California Creek (RM034). The Rocky Creek placer was one of the richest in the upper Tuluksak River drainage. About 2 miles of the creek from the mouth to the headwaters have been mined, much of it by dredging. The grade of the deposit increased upstream. The bedrock in the drainage is thermally metamorphosed Jurassic volcanic rocks that are intruded by a mid-Cretaceous granitic stock at the head of the drainage (Box and others, 1993). The placer appears to continue upstream to near the contact zone of the granitic stock.
Workings: About 2 miles of the creek have been placer mined, much of it by dredging.
Age: Quaternary.
