Location: Placer claims on Landslide Creek, a south tributary to the Oshetna River, extend upstream for about 2 1/2 miles from its mouth. The coordinates are at an elevation of about 3,700 feet. The location is accurate to within 1/2 mile.
Geology: Upper Landslide Creek drains an area of Tertiary volcanic rocks and Quaternary landslide deposits (Kurtak and others, 1992). The lower part of the drainage is underlain by Talkeetna Formation volcanic rocks, sandstone(?), and argillite; Tertiary fluviatile conglomerate; a Jurassic intrusion; and Quaternary landslide and glacial deposits. Gold occurs in the alluvial gravel deposits which are up to 400 feet wide and 20 to 40 feet thick (Kurtak and others, 1992). A placer sample collected by the U.S. Bureau of Mines contains no gold (Kurtak and others, 1992).
Workings: Twenty-five claims were staked in 1982 (Kurtak and others, 1992). A placer sample collected by the U.S. Bureau of Mines contains no gold (Kurtak and others, 1992).
Age: Quaternary.
Reserves: An estimated 1.5 million cubic yards of alluvial material are in the drainage (Kurtak and others, 1992).
