2011 Map of Forbidden Peak

About this map

Forbidden Peak and the high glaciated summits of Skagit County dominate this 2011 survey, illustrating a landscape defined by ice and vertical relief. The map documents an extensive network of alpine ice bodies, including the massive Boston Glacier, Inspiration Glacier, and the Borealis Glacier. Below the peaks of Mount Torment and Austera Peak, the hydrology of the North Cascades is revealed through the headwaters of Thunder Creek and McAllister Creek. Evidence of human activity in this demanding environment is sparse but significant, centered on the Skagit Queen Mine and seasonal shelters such as Meadow Cabins and Rock Cabin. The topography here, marked by Boston Basin and Klawatti Lake, represents a modern record of one of the most heavily glaciated regions in the contiguous United States.
