Location: Bittenbender and others (1999, fig. 12) and the US Bureau of Land Management (2002; MAS no. 0021140018) locate the Boston claim at an elevation of about 500 feet in the SW1/4NE1/4 sec. 4, T. 56 S., R. 64 E. Cobb (1972, 1978) locates it at an elevation of about 100 feet about 0.8 mile to the southwest, in the NW1/4 sec. 9, same township and range. For this record, the site is plotted at the location of Bittenbender and others and U.S. Bureau of Land Management.
Geology: The rocks in the vicinity of the Boston prospect are part of the Cretaceous Sitka Graywacke which consists mainly of graywacke and argillite (Loney and others, 1975). Little is known about the Boston prospect other than that a claim was staked here and some samples contained a trace amount of gold (Wright and Wright, 1905; Knopf, 1912, Nelson, 1931). It was not found by Bittenbender and others (1999).
Workings: Little is known other than that a claim was staked here before 1905. There is no indication of recent work.
Age: Cretaceous or younger based on the age of the host rock.
