Location and accuracy	This occurrence is located on top of the ridge between Crevice and McCamant Creeks, about 2.3 miles southeast of the confluence of McCamant Creek and Allen River. The occurrence is at an elevation of about 2,700 feet in the NE1/4 section 1, T. 29 N., R. 20 W., of the Fairbanks Meridian. The site is sample 303 in Dillon and others (1981 [AOF 133B]). The location is accurate.

Geologic setting

Geologic description This occurrence consists of galena and malachite in maroon and white, muscovite quartzite (Dillon and others, 1981 [AOF 133B]). An analysis of a composite rock sample, however, showed no anomalous metal values. The rocks in the area consists of Devonian, Hunt Fork Shale near its thrust contact with overlying Devonian, Skajit Limestone (Dillon and others, 1986). A small area of Devonian(?) siliceous, clastic rocks is nearby. No other information is available.
