About this map

The international boundary between Alaska and British Columbia runs through the heart of the Portland Canal, defining the eastern edge of this coastal wilderness. Most of the terrain is occupied by the Tongass National Forest, where the elevations rise sharply from the waterline toward the high peaks of the Peabody Mountains. The landscape is carved by steep drainages and glacial features, characteristic of the remote maritime forests of the Alexander Archipelago. Along the shoreline, navigators encounter distinct landmarks such as Turn Point and the sheltered waters of Tombstone Bay. This survey captures the topographical complexity of the fjords and mountains before they transition into Canadian territory, providing a precise look at the drainage patterns of Donahue Cr and Helen Cr as they meet the deep waters of the canal.
