Tongass National Forest dominates this section of the Coast Mountains, where ice and rock define the landscape in the early 21st century. The topographic survey documents the massive expanse of the Baird Glacier alongside the smaller Witch Glacier, providing a detailed record of glacial extent and elevation during this period. A notable terrestrial landmark known as The Oasis sits surrounded by the complex contour lines of this high-altitude environment, offering a specific point of reference within the broader wilderness. This 2021 update utilizes modern elevation data and imagery to chart the shifting boundaries of the ice fields in one of the most remote corridors of the Alaska panhandle.
