2018 Map of Sumdum C-3 NE
USGS Topo · Published 2018About this map
Boundary Peak 76 stands as a prominent marker along the international line where the high wilderness of the Tongass National Forest meets the border of Canada and the United States of America. This 2018 survey documents a landscape defined by extreme elevation and high-altitude terrain, where the Public Land Survey System grids of t47s r78e, t48s r78e, and t49s r78e terminate against the diagonal boundary. The map illustrates the literal edge of American territory in the Alaskan panhandle, capturing the precise points where administrative townships and ranges dissolve into the alpine frontier of British Columbia.
