Geographic coordinates

Geographic coordinates: -166.26438, 65.33128 (WGS84)
Relative position Sunset Creek is a southwest-flowing stream whose mouth is on the north shore of Grantley Harbor, 4 miles northeast of Teller and 6.25 miles southeast of Brevig Mission. Placer mining operations took place 1.4 to 2.1 miles upstream from the mouth at surface elevations of about 40 to 110 feet (Sainsbury and others, 1969). This is locality 66 of Cobb and Sainsbury (1972). Cobb (1975) summarized relevant references under the name 'Sunset Cr.'.

Comments on the geologic information

  • Geologic Description = Bedrock in the Sunset Creek drainage is a chlorite and mica schist assemblage that is locally intruded by small greenstone bodies (Sainsbury, 1972); the age of this assemblage is uncertain but it is probably Paleozoic. Quaternary basalt flows are present at higher elevations in some headwater areas. Small quartz veins are common in the schist bedrock. The placer gold deposit , at least locally high grade, is in a few to several feet of fine gravel on schist and greenstone bedrock that also contains gold in the upper three feet. Scheelite was abundant enough to have been saved during some operations. Mining took place at several different times between 1901 and 1946 and employed several different methods, including dredging and hydraulicking (Cobb, 1975).The deposit is at elevations where Quaternary marine transgressions may have modified the alluvial placer (Sainsbury and others, 1969).
