2021 Map of Sumdum A-2 NE

About this map

The Tongass National Forest dominates this landscape within the Coast Mountains, where high-elevation glacial activity is the primary driver of the terrain. The presence of the massive Baird Glacier and the distinctively named Witches Cauldron indicates a region defined by moving ice and permanent snowfields. These features, along with Oasis Glacier, illustrate the complex drainage and ice-flow patterns typical of the Alaska-British Columbia borderlands. The map reveals the intricate contouring of high peaks and ice-filled basins, where the shifting boundaries of glaciers like the Baird Glacier shape the hydrology and physical accessibility of this wilderness. This 2021 topographic record serves as a precise baseline for researchers monitoring glacial retreat and alpine landforms in one of the most significant temperate rainforest and mountain ecosystems in North America.
