About this map

Yellowstone National Park encompasses this high-altitude landscape where the vast waters of Yellowstone Lake meet a series of complex shorelines and islands. The northern portion of the map is defined by the sweeping curve of the Grand Loop Road-West Thumb-Fishing Bridge, which traces the shoreline near Sand Point and Rock Point. This thoroughfare serves as the primary artery for movement through the park's interior, connecting the geothermal interest of West Thumb with the northern reaches of the lake.

Further south, the terrain becomes more sequestered, characterized by the landlocked Delusion Lake and the intricate peninsulas ending at Wolf Point and Snipe Point. The lake itself is punctuated by isolated landmasses such as Dot Island and the larger Frank Island, while deep inlets like Eagle Bay and the Flat Mountain Arm demonstrate the irregular, glacial-carved nature of the shoreline. Small tributaries like Weasel Creek drain the higher elevations, feeding the massive lake basin that dominates the regional hydrology.
