1985 Map of Yakutat C-1

About this map

Tongass National Forest covers the mountainous terrain of the Saint Elias Mountains in this 1985 survey, where the landscape is defined by massive ice fields and glacial movements. The international border between Canada and the United States and the regional boundary between British Columbia and Alaska bisect the rugged peaks, illustrating the remote geopolitical intersection of the Pacific Northwest. The presence of numerous Glacier features and a prominent Moraine highlight an environment shaped by heavy glaciation. This map, compiled from 1958 aerial photography, records the physical state of these ice masses before late twentieth-century shifts, providing a topographic baseline for the region’s high-altitude geography and federal reservation boundaries established by the Alaska National Interest Lands Conservation Act.
