Location and accuracy This placer prospect is in the valley of an unnamed, east headwater tributary to Trail Creek. It is at an elevation of about 4,800 feet, 6,000 feet northwest of peak 7080, and 5,000 feet southwest of elevation 6285. The prospect is about 0.4 mile west of the center of section 30, T. 10 N., R. 12 E. of the Copper River Meridian. This is locality 3 of Richter and Schmoll (1973), locality 61 of Richter and others (1975), and National Park Service locality WRST-7 (unpublished data). This prospect was included by Cobb and Richter (1980) under the name 'Trail Cr.'. It is located to within a few hundred feet.

Geologic setting

Geologic description

Placer gold claims were staked at this locality in 1931 and subsequently prospected without encouraging results (Moffit, 1943). Some surface placer workings are present (Richter and others, 1975). Bedrock in this tributary to Trail Creek includes abundant Upper Jurassic argillite in its headwaters and Triassic limestone and greenstone downstream. Fine-grained dioritic dikes and irregular intrusions are widespread in the bedrock of this drainage (Richter and Schmoll, 1973 ).
