About this map

Le Conte Glacier dominates this 1961 topographic study of the Alaskan wilderness near the Canadian border. The map documents a dramatic glacial landscape within the Tongass National Forest, where the immense ice flows of Shakes Glacier and the Popof Glacier carve through the coastal range. The international boundary between the United States and Canada is precisely delineated, passing through high-altitude landmarks such as Boundary Peak 69 and Mount Pratt.

A significant portion of the area is designated as the Stikine-Le Conte Wilderness, illustrating the region's preservation long before modern climate shifts altered these ice fields. Below the towering heights of Castle Mountain, the meltwater from the Shakes Glacier feeds directly into Shakes Lake, providing a clear record of the hydrological connections in this uninhabited part of Southeast Alaska.
