2018 Map of Sumdum A-2 NW
USGS Topo · Published 2018About this map
Baird Glacier and Sills Glacier dominate this remote Alaskan landscape within the Tongass National Forest. Located in the Coast Mountains, the terrain is defined by extreme elevation changes and vast ice fields that suggest a dynamic environment of glacial movement and meltwater. A peculiar feature known as The Oasis stands out amidst the high-altitude ice, indicating a unique topographical or ecological break in the frozen surroundings. This 2018 survey by the U.S. Geological Survey provides a precise record of the ice margins and contour lines during an era of significant glacial transition in the Petersburg Borough region.
