About this map

The Coast Mountains dominate this 1955 survey of the international boundary between Alaska and British Columbia. This landscape is defined by massive ice fields and drainage systems, where the Stikine River and Unuk River carve deep valleys through the Tongass National Forest toward the Pacific. The intricate coastline features the Bradfield Canal and Ernest Sound, providing essential maritime access to this otherwise inaccessible terrain.

Glacial activity is evident throughout the sheet, from the Mud Glacier in the north to the Frankmackie Glacier near the eastern border. These frozen heights are punctuated by named peaks like Mt Whipple and the Kapho Mountains. The mapping of remote waterways such as the Chickamin River and South Fork illustrates the importance of river navigation and shoreline resources like Anan Bay and Burroughs Bay during the mid-century era.
