Portland Canal serves as the focal point of this coastal boundary survey, where the international line between Canada and the United States Of America follows the deep-water passage. The landscape is characterized by the extreme verticality of the Tongass National Forest, which rises sharply from the eastern shore to prominent landmarks like Cliff Point and Slab Point. The network of drainages feeding into the canal includes the Georgie River, E Georgie River, and Outram Cr, illustrating a wild and largely undeveloped maritime environment. This mapping detail provides an essential look at the physical geography of the Alaska-British Columbia border, capturing the intricate shoreline and tributary systems that define the rugged interface between these two nations in the early 21st century.
