Older references to California Creek refer to what is now called upper Tuluksak River (RM028) on USGS topographic maps.
Location: California Creek is a headwater tributary of the Tuluksak River. The creek has been placer mined over at least 3 miles upstream from its mouth. The map site, near the mouth of Rocky Creek, is the approximate midpoint of the placer tailings. It is in the NW1/4 sec. 10, T. 11 N., R. 60 W., of the Seward Meridian. California Creek is included in locality 17 of Hoare and Cobb (1972, 1977).
Geology: California Creek is an important placer-gold producing tributary to the upper Tuluksak River. At least 3 miles of California Creek have been extensively dredged, including about on-half mile of the lower creek along the Tuluksak River valley. Dredging continued for about 1.5 miles upstream of the mouth of Rocky Creek (RM027), and some mining may have taken place for another mile to the headwaters of California Creek. Most of the California Creek drainage is underlain by thermally metamorphosed Jurassic volcanic rocks along the east side of a large mid-Cretaceous granitic pluton (Box and others, 1993).
Workings: Dredge tailings cover about 5.6 miles of the California Creek drainage, including about one-half mile of the lower creek along the Tuluksak River valley. Dredging continued for about 1.5 miles upstream of the mouth of Rocky Creek (RM027), and some mining may have taken place for another mile to the headwaters of California Creek. The tailings have an average width of anout 0.15 mile and a maximum width of 0.4 mile near the mouth of the creek. Much of the mining took place from about 1947 to 1960 (Hoare and Cobb, 1977). Additional mining took place in the late 1980's.
