Location: Keefer Creek is an approximately 7-mile-long south tributary to the Mulchatna River. Its confluence with the Mulchatna River is about 7 miles upstream from the mouth of Mosquito River, a north tributary to the Mulchatna River. This occurrence is very approximately located, probably within several miles. For this record, the map site is on Keefer Creek at the north border of section 9, T 2 N, R 39 W, of the Seward Meridian. The occurrence was referred to as 'Keefer Creek' by Cobb (1972 [MF 384]).
Geology: A written communication from F. H. Waskey (1935), probably to J. B. Mertie Jr., reported that placer gold had been identified on Keefer Creek (Cobb, 1972 [MF 384]). Keefer Creek is an approximately 7-mile-long south tributary to the Mulchatna River. The Mulchatna River approximately coincides with a major structural boundary between mid-Cretaceous Kuskowim Group clastic rocks to the west and Mesozoic sedimentary and igneous rocks to the east (Decker and others, 1994).
Age: Quaternary.
