2021 Map of Sumdum D-3 SE

USGS Topo · Published 2021

About this map

The international border between the Canada and the United States of America cuts through this isolated section of the Coast Mountains. This 2021 survey illustrates a remote wilderness where the high peaks and glaciers of the Tongass National Forest meet the Canadian frontier. The map is defined by extreme verticality and the absence of human infrastructure, focusing instead on the natural topography of the glacial landscape. It captures a specific section of the border within township t47s r78e, documenting the precise line where these two nations meet amidst the ice and rock of the Alaskan panhandle.
