Location and accuracy The placer prospect is in the S1/2 section 34, T. 10 N., R. 2 E., of the Seward Meridian. Kern Creek flows southwest into Turnagain Arm about 6 miles south 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), and location P-95 of Jansons and others (1984). The location is accurate to within 300 feet.

Geologic setting

Geologic description

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).

Production and reserves

Workings or exploration
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 commercial potential for mechanized operations and suction dredging (Jansons and others, 1984).
Indication of production Undetermined
Production notes It is unknown if there was any production.
