|Location and accuracy||Coyote Creek is a north-flowing stream whose mouth is on the south shore of Grantley Harbor, 1.75 miles southeast of Teller. Mining operations as mapped by Sainsbury and others (1969) took place along 0.6 miles of the main drainage between elevations of 245 and 320 feet. This is locality 85 of Cobb and Sainsbury (1972). Cobb (1975) summarized relevant references under the name 'Coyote Cr.'.|
Geologic descriptionBedrock in the Coyote Creek drainage is a metapelitic sequence with local metamorphosed mafic intrusive bodies (Sainsbury, 1972). In places, the retrograded greenschist facies mafic bodies preserve remnant blueschist facies minerals. The age of this assemblage is unknown but it is probably Paleozoic. Placer mining operations have taken place along 0.6 miles of the main drainage between elevations of 245 and 320 feet (Sainsbury and others, 1969). These non-float operations took place primarily between 1920 and 1940 (Cobb, 1975). The character of the placer deposit has not been described.
