2024 Map of Sumdum A-1 SE
USGS Topo · Published 2024About this map
Kates Needle towers over this remote borderland where the Pacific Northwest meets the interior, marking a sharp topographic divide along the Canada United States of America boundary. The southern portion of the sheet is dominated by the high-elevation protected lands of the Stikine-Leconte Wilderness and the Tongass National Forest, characterized by steep glaciated terrain and dramatic relief. Because this area remains largely untouched by infrastructure, the map serves as a primary record of the international boundary line as it traverses these peaks, providing essential context for the shared wilderness management between Alaska and British Columbia.
