Location: This occurrence is about 0.4 mile north-northwest of the top of Camelback Mountain at an elevation of about 2,100 feet. It is about 0.3 mile north of the center of section 1, T. 28 N., R. 44 W., of the Seward Meridian. The location is accurate.
Geology: This occurrence is a zone of iron-stained shale in the hornfels aureole of the 73.2 Ma, Camelback Mountain intrusion (Bundtzen and others, 1988; Miller and Bundtzen, 1994; Miller, Bundtzen, and Gray, 2005). The mineralized shale is about 15 meter thick as inferred from rubble crop. One grab sample contained 5,100 parts per billion (ppb) mercury and 100 ppb silver (Bundtzen, Laird, and Lockwood, 1988).
Workings: Surface samples were collected by the Alaska Division of Geological and Geophysical Surveys in 1983 (Bundtzen, Laird, and Lockwood, 1988).
Age: Undated; probably related to the nearby Camelback Mountain intrusion that is 73.2 Ma (Bundtzen, Laird, and Lockwood, 1988).
Alteration: Iron oxidation.
