About this map

Yellowstone National Park dominates this remote shoreline terrain, where the eastern edge of Yellowstone Lake meets the Absaroka foothills. The landscape is defined by the deep indentation of the Southeast Arm and the massive landform of The Promontory, which juts into the water to create a complex series of coves and points. These include Signal Point, Park Point, and Elk Point, providing natural landmarks along the lakeshore that have guided travelers for generations.

The historical Thorofare Trail provides the primary overland corridor through this wilderness, tracing the rugged lake margin and crossing drainage systems like Clear Cr and Meadow Cr. Just offshore, the isolated Frank Island and the southern Plover Point stand as distinct features within the massive high-altitude lake. This map documents a stretch of the park where the absence of roads emphasizes the importance of established backcountry routes and the natural geometry of the shoreline.
