About this map

Port Houghton and the adjacent Sandborn Canal dominate this coastal landscape, revealing the intricate shoreline of Southeast Alaska as it appeared based on data from the late 1940s and mid-1950s. The map illustrates a wilderness characterized by dramatic elevation changes, from the waters of the North Arm to the heights of Washington Peak and VABM 5156 Triple C.

Evidence of human presence is minimal, centered primarily on the Walter Island Cabin located on Walter Island. This structure provides a rare point of reference for researchers and historians looking for early shelters or maritime outposts in this region. The complex hydrology of the area is further detailed by the Chuck River, which feeds into The Salt Chuck, and the presence of a significant Tidal Flat at the head of the inlet, indicating the dynamic nature of the local environment.
