|Location and accuracy||This occurrence is at an elevation of about 1,200 feet in Devils Canyon of the Susitna River. It is on the north wall of the canyon near the tip of a prominent bend in the river in the NE1/4 sec. 32, T. 32 N., R. 1 E., Seward Meridian. The location is accurate to within 1/2 mile.|
Geologic descriptionThis rocks in the area are dark gray to black argillite, lithic graywacke, and polymictic pebble conglomerate, with a few thin beds of chert and limestone (Kurtak and others, 1992). An iron-stained rhyolite dike cuts silicified and pyrite-bearing argillite. Selected samples contain up to 2 parts per million silver, 209 parts per million copper, and 205 parts per million zinc (Balen, 1990).
