About this map

Eastern Passage dominates the central corridor of this coastal Alaskan landscape, separating the forested heights of the mainland from the surrounding islands. Within the Tongass National Forest, the terrain rises steeply from the shoreline toward named peaks like The Eye Opener. This 2021 survey illustrates a wilderness defined by its water systems, from the expansive Virginia Lake in the northeast to the descent of Rainbow Falls and the drainage of Institute Creek.

Modern infrastructure is limited to peripheral tracks such as Spur Road, East Pass, and the evocative Old Hermit trail. The map details the interface between the maritime environment and the dense interior, marked by features such as Babbler Point and the mouth of Pats Creek. These labels suggest a landscape where navigation and resource management are dictated by the dramatic verticality of the coastal range.
