Location and accuracy Eureka Creek is a west tributary to Dominion Creek (BH012), a west tributary to Salmon River. The headwaters of Eureka Creek are on the west side of Marvel Dome. For this record, the map site is arbitarily placed at the trailhead on the middle part of the creek, in the NW1/4 of section 10, T. 10 N., R. 58 W., of the Seward Meridian (USGS Bethel D-2 topographic map, 1979 edition). Hoare and Cobb (1977) included this location under the name 'Eureka Ck.'.

Geologic setting

Geologic description

Eureka Creek heads on Marvel Dome, where an Upper Cretaceous granitic stock is surrounded by hornfels in sedimentary rocks of the mid-Cretaceous Kuskokwim Group (Box and others, 1993). Placer gold has been found on the creek, but mining apparently has not occurred (Hoare and Cobb, 1977). A small glacier occupied the upper part of Eureka Creek valley, and outwash deposits, including many boulders, fill the lower part of the valley (Maddren, 1915, p. 339). The outwash deposits are incised by the present stream.
