About this map

The Tongass National Forest along the international border between Alaska and British Columbia is defined here by massive ice fields and deep river valleys. This mid-century survey reveals a landscape of high alpine peaks such as Mt Blaine and Mt Willibert overlooking an intricate system of moving ice. Significant glacial features including Clarasmith Glacier and the Gracey Creek Glacier feed into the lowlands, while the Chickamin River and King River carve paths through the heavily forested terrain. The map records the precise boundary between the Canada and the United States, passing through landmarks like Mt John Jay and Mt Upshur. This record is particularly valuable for its depiction of the Chickamin Glacier and Through Glacier at a time before significant modern warming began to reshape these perennial ice bodies.
