1955 Map of Bradfield canal A-2

About this map

The Tongass National Forest dominates this mid-century survey of the Alaska-Canada borderlands, where massive ice fields and river valleys define the landscape. The international boundary line is anchored by several high peaks, including Mt Willibert, Mt John Jay, and Mt Upshur. Below these summits, the drainage systems of the Leduc River and Chickamin River carve through the wilderness, fed by numerous ice bodies such as the Gracey Creek Glacier and the Chickamin Glacier. This map documents a transitional period for the region, reflecting topography from 1948 aerial photography with 1955 field annotations. The environment is one of active glaciation and steep relief, with Through Glacier and Clara Smith Glacier illustrating the immense volume of ice covering the mountain passes before the era of modern glacial retreat.
