2018 Map of Sumdum A-1 SW

About this map

LeConte Glacier dominates the upper reaches of this international boundary zone where Alaska meets British Columbia. Situated within the protected expanse of the Tongass National Forest, the landscape is defined by high-altitude glacial ice and steep contour lines that illustrate the dramatic elevation shifts of the Coast Mountains. The map clearly delineates the United States-Canada border, providing a precise look at how the geopolitical line bisects these icefields. Because this is a high-latitude wilderness area, the map is remarkably sparse of human infrastructure, focusing instead on the physical geography and the natural movement of ice through the rugged terrain. Researchers and glaciologists can use this survey to examine the footprint of the glacier and its surrounding peaks as they stood in the early twenty-first century.
