Location and accuracy Tincan Creek is located in T. 8 N., R. 1 and 2 E., of the Seward Meridian. The map site of this placer mine is in the SW1/4 section 13, T. 8 N., R. 1 E. It is situated on the east side of the Seward Highway about 2 miles south of the rest area in Turnagain Pass. This location is accurate to within 300 feet. This is location GC14 of Jasper (1967), location 151 of Cobb and Richter (1972), location 151 of Cobb and Tysdal (1980), and location P-67 of Jansons and others (1984).

Geologic setting

Geologic description

Tincan Creek drains small glaciers on the northwest side of Kickstep Mountain and Tincan peak. Bedrock in the area is slate and graywacke of the Upper Cretaceous Valdez Group (Nelson and others, 1985).
Gravels in the lower section of the creek were hand placered in the 1930s (Jansons and others, 1984). Little gold occurs throughout the gravels, which are poorly sorted and have a high clay content. Accessory minerals identified in concentrates are scheelite and chalcopyrite (Jasper, 1967).
Estimated total production is between 50 and 100 ounces of gold (Jansons and others, 1984).
