The international boundary between Canada and the United States defines the character of this remote landscape, where the Alaska Juneau Borough meets the wilderness of British Columbia. This high-altitude terrain is dominated by massive ice fields and glacial systems within the Tongass National Forest. Notable features include the expansive Bacon Glacier and the E Twin Glacier, which sit alongside an unnamed Unknown Glacier. The drainage patterns are dictated by these ice masses, with Boundary Cr flowing through the southern portion of the survey. The map provides a precise look at the 2017 topography of these glaciers, documenting the ice extent and elevation contours at a point when such features are subject to significant environmental change. The lack of human infrastructure or roads underscores the extreme isolation of this mountainous border region.
