The site is at Alaska Division of Geological and Geophysical Surveys (ADGGS) sample station 97SL153 (Liss and others, 1998), near the northwest corner of section 18, T. 2 N., R. 16 W., of the Fairbanks Meridian. The location is accurate within 500 feet.
Geology: Bedrock at this occurrence is mainly Lower Cretaceous sandstone, shale, and siltstone (Reifenstuhl and others, 1998). The western contact of the Tertiary Hot Springs granite pluton is 2 miles to the east. Samples (97SL153B and 97SL153C) of a felsic dike and of iron-stained shale on the south side of Big Denver Creek contained one or more of the following maximum values: 2,230 parts per million (ppm) copper, 266 ppm arsenic, 13.55 percent iron, 3,130 ppm phosphorous, and 14 ppm scandium (Liss and others, 1998). There is no record of exploration or mining at this site.
