Location: A Au-Cu placer prospect is in the S½ sec. 34, T10N, R2E, Seward Meridian. Kern Creek flows SW into Turnagain Arm about 6 miles S of Girdwood (which is misspelled on the 1994 edition of the D-6 map). This is locations 135 and 136 of Cobb and Richter (1972), location 162 of MacKevett and Holloway (1977), locations 135 and 136 of Cobb and Tysdal (1980), location P-95 of Jansons and others (1984), and location SR048 of Huber and Huber (2005). The location is accurate to within 300 feet.
Mineralization: A Quaternary placer Au deposit (Deposit Model: Placer Au (alluvial) (Cox and Singer, 1986); model: 39a).
Geology: Kern Creek drains an area underlain by sedimentary rocks of the Valdez Group of Late Cretaceous age (Nelson and others, 1985). A trace amount of gold occurs in the stream gravels (Capps, 1916), and a pan concentrate contained chalcopyrite (Jasper, 1967). Kern Creek occupies a steep, narrow, avalanche- and debris-filled valley with numerous falls and cascades. There is little accumulation of alluvial gravel until its junction with Turnagain Arm (Jansons and others, 1984).
Workings: Capps (1916) reported that Kern Creek was prospected in 1898 and 1903. Some gold was recovered but not enough to warrant mining. A pan concentrate sample contained chalcopyrite (Jasper, 1967). The U.S. Bureau of Mines collected samples that contained only trace amounts of gold. Kern Creek is believed to have low commericial potential for mechanized operations and suction dredging (Jansons and others, 1984).
Production: It is unknown if there was any production.
