1961 Map of Sumdum C-2

USGS Topo · Published 1985

About this map

Boundary Peak 75 7776 stands as a primary survey marker on the international boundary between Alaska and British Columbia during the early 1960s. This survey, conducted by the Geological Survey and the International Boundary Commission, documents the remote coastal topography where the United States and Canada meet. The landscape is dominated by the steep fjord systems of Tracy Arm and Fords Terror, situated within the sprawling Tongass National Forest. The map illustrates the glacial character of the region, specifically focusing on the protected lands of the Fords Terror Wilderness. This 1961 record provides an essential view of the untouched maritime wilderness before later administrative revisions, capturing the precise line where coastal Alaska transitions into the high peaks of British Columbia.
