About this map

Tongass National Forest dominates this Alaskan landscape, where glacial meltwater and complex drainage systems define the geography of the Coast Mountains. The interior is accessible primarily by traditional routes like the Patterson River Trl and Muddy River Trl, which follow the natural contours of the river valleys. A network of significant waterways, including the North Blind River and Muddy River, meanders through the coastal lowlands toward the shoreline near Ruth Island. High-elevation landmarks such as Pirate Peak and Patterson Peaks overlook a series of remote water bodies like Ess Lake, Ruth Lake, and Brown Cove Lake. The mapping reflects a region where the natural environment remains the primary structure, with survey lines and township markers providing the only modern administrative overlay across the wilderness.
