|Location and accuracy||Much of Ship Creek occupies a steep, narrow, bedrock valley. The creek crosses a short, narrow, flood plain and drains into the lower end of Kenai Lake. The gold-bearing section of the creek is about a mile long; it is in sections 6 and 7, T. 3 N., R. 1 W. of the Seward Meridian. The map location is in the center of the placer section. This is location P-54 of Jansons and others (1984). This location is accurate to within a quarter of a mile.|
Geologic descriptionBedrock in the Ship Creek drainage is sedimentary rock of the Valdez Group of Late Cretaceous age (Nelson and others, 1985). The placer gold occurs in pooly stratified and washed alluvium in the stream channel and in local bench deposits that consist of clay-rich, cemented glacial or fluvial-glacial gravel. The gravel contains abundant slate cobbles (Jansons and others, 1984). The clay-rich gravels contained relatively coarse (0.187-inch) gold at one sample site. Four suction dredge samples yielded from a trace to 0.0081 ounce of gold per hour (Jansons and others, 1984).

|Mineral deposit model||Placer Au (Cox and Singer, 1986; model 39a)|
|Mineral deposit model number||39a|
|Age of mineralization||Quaternary; the gold is in the current stream channel and in bench gravel.|
|Workings or exploration||There are some abandoned hand workings near the mouth of the creek. The clay-rich gravels contained relatively coarse (0.187 inch) gold at one sample site. Four suction dredge samples yielded from a trace to 0.0081 ounce of gold per hour (Jansons and others, 1984). Recreational suction dredging occasionally occurs on this creek.|
