Geologic setting

Geologic description

The rocks along Flat Creek are Paleozoic amphibolite-facies gneiss and amphibolite (Foster, 1976). Extensive Quaternary terrace and alluvial gravel deposits are present near the mouth of Flat Creek; these terraces are as much as several hundred feet above the creek (Foster and Keith, 1968).
Placers at Flat Creek were mined in 1908 (Brooks, 1909). Little work was done on Flat Creek in 1911 due to low water (Porter, 1912), and little progress was made on Flat Creek in 1912 (Ellsworth and Davenport, 1913). Mining occurred on Flat Creek in 1915 (Brooks, 1916). There has been placer gold production on the lower Fortymile River (see also EA071) near the mouth of Flat Creek.
