This prospect is now within the city of Sitka on private land.
Location: The location of this prospect(?) is known only approximately to be at an elevation of about 100 feet, 0.6 mile east of Harbor Point and south of Starrigavan Bay. For this record, it is plotted 0.5 mile west-northwest of the southeast corner of sec. 3, T. 55 S., R. 63 E. It is MAS no. 0021140192 (U.S. Bureau of Land Management, 2002).
Geology: This prospect may be on either side of a major northwest-striking fault that separates rocks of the Triassic or Jurassic, Khaz Formation to the east from rocks of the Jurassic and Cretaceous, Sitka Graywacke to the west (Loney and others, 1975). The Khaz Formation is a heterogeneous unit that consists of greenstone, graywacke, greenschist, metachert, phyllite, and minor limestone. The Sitka Graywacke consists mainly of graywacke and argillite. The only information about this prospect is that a lode claim for gold was staked there (U.S. Bureau of Land Management, 2002).
Workings: The only evidence of workings is that a claim was staked here.
Age: Triassic or younger based on the age of the host rocks.
