Leduc River and the Chickamin River carve through this high-altitude landscape along the international boundary between Canada and the United States. The mid-century survey illustrates an environment defined by expansive ice fields and named peaks, where the British Columbia border is marked by a series of geodetic monuments atop summits like Mt Willibert and Mt. Upshur. The drainage patterns are dominated by massive glacial systems, including the Clara Smith Glacier and Through Glacier, which feed into the primary river valleys. This map captures the region before the formal designation of the Misty Fiords National Monument, showing the land as part of the broader Tongass National Forest. The absence of roads or permanent settlements highlights the isolation of this borderland, where travel was dictated by watercourses and the shifting margins of the Chickamin Glacier.
