|Location and accuracy||This occurrence is at an elevation of about 1,150 feet in a unnamed creek that flows south from Granite Mountain. The occurrence is about 0.8 mile east-southeast of hill 2210 and about 0.3 mile northeast of the center of section 5, T. 25 N., R. 40 W., of the Seward Meridian. The location is accurate.|
Geologic descriptionVisible gold was found in a nonmagnetic, heavy mineral concentrate collected in an unnamed creek flowing south from Granite Mountain. The rocks in the vicinity are hornfels derived from the Upper Cretaceous, Kuskokwim Group, and granitic rocks from the Cretaceous Granite Mountain pluton (Miller and Bundtzen, 1994; Miller, Bundtzen, and Gray, 2005).
