Forbidden Peak and the high alpine terrain of the North Cascades National Park dominate this survey of Washington's glaciated wilderness. The map details an environment shaped by massive ice fields and steep drainages, including the expansive Inspiration Glacier, Boston Glacier, and the North Klawatti Glacier. These frozen features feed several major water systems, most notably Thunder Cr and its forks, as well as high-altitude water bodies like Klawatti Lake and Moraine Lake.
