2018 Map of Sumdum A-1 SE

About this map

The international border between Canada and the United States cuts across the high-altitude terrain of this 2018 survey, centered on the boundary between Alaska and British Columbia. Much of the American side of the line is occupied by the protected lands of the Tongass National Forest, characterized by steep elevation changes and the massive ice field of the Leconte Glacier. The prominence of Kates Needle stands at the edge of the survey area, serving as a significant landmark on the continental divide and maritime boundary. This map emphasizes the physical geography and administrative divisions of a remote trans-border region, where the Public Land Survey System markers for t55s r84e and t56s r84e provide a grid for tracking land rights and wilderness management in a landscape shaped by glacial activity.
