Location and accuracy The location of this placer prospect is only known approximately to be at about sea level on the west side of Klag Bay near the ruins of the town of Chichagof. For this record, the prospect is plotted at the dock of the townsite in the SE1/4 sec. 36, T. 48 S., R. 57 E. It is MAS no. 0021140124 (U.S. Bureau of Land Management, 2002).

Geologic setting

Geologic description

Johnson and Karl (1985) map the rocks in the area of this prospect as Cretaceous graywacke and argillite interbedded with sparse, lenticular beds of basalt. The rocks are cut by numerous high-angle, mainly northwest-striking faults. They include the extension of the fault at the Chichagof Mine (SI093) which passes through this prospect. The only published information about this prospect is that it has been staked for placer gold (U.S. Bureau of Land Management, 2002).
