1948 Map of Skagway C-3

About this map

Glacial valleys and braided river systems define this high-altitude borderland where the Canada United States boundary follows the crests of the Coast Mountains. The Chilkat River serves as the primary drainage corridor, fed by a network of tributaries including the Kelsall River and the braided Tahini River. The map reveals a landscape dominated by massive peaks like Tohitkah Mountain and Mt Raymond, which overlook the deep alluvial valleys that have long served as passage routes through the interior. Surveyed just after the war years using aerial photography, the sheet records the intricate topography of ice fields and seasonal waterways that surround Klukwah Mountain and Klutshah Mountain. This technical record by the U.S. Geological Survey also notes the Chilkoot River corridor to the east, providing a foundational look at the undeveloped wilderness before modern infrastructure reached these northern reaches.
