|Location and accuracy||This is a north-flowing, south tributary to the Agiapuk River in the northeast Teller B-3 quadrangle. Sainsbury and others (1969) mapped the presence of placer mining operations between surface elevations of 240 to 250 feet on an east tributary whose confluence with the main drainage is 2.5 miles upstream from the Agiapuk River. This locality was not included in the compilation of Cobb and Sainsbury (1972). Cobb (1975) summarized Sainsbury and others (1969) under the name 'Unnamed creek'.|
Geologic descriptionBedrock in this 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. All that is known about this locality is that some placer mining operations took place along the lower 0.5 miles of the east tributary (Sainsbury and others, 1969).
