About this map

The international maritime boundary between the United States and Canada defines this 1955 survey of the rugged Alaska panhandle. Steep coastal topography characterizes the Tongass National Forest, where heavy-timbered slopes rise abruptly from the deep waters of the Portland Canal and Pearse Inlet. Notable peaks such as Dome Mountain and Stripe Mountain dominate the skyline above complex glacial and fluvial features like the Harrison Lakes and the Tidal Flat at Hidden Inlet.

Coastal navigation points are precisely marked along the British Columbia border, including Blunt Pt, Petrel Pt, and Spit Pt. The drainage patterns of Harrison Creek and the isolated waters of Reef Lake illustrate the interior geography of this wilderness area before significant modern development. This sheet preserves the mid-century state of the coastline as compiled from early photogrammetric methods and hydrographic charts from the 1950s.
