Geologic setting

Geologic description

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).
