About this map

Yellowstone Lake dominates this 2017 topographic survey, specifically focusing on the geothermal activity surrounding the West Thumb caldera. The hydrothermal features of the West Thumb Geyser Basin are documented in remarkable detail, including Fishing Cone and Abyss Pool. Thermal diversity is evident across the shoreline, with Potts Hot Spring Basin to the north and numerous individual springs like Big Cone Spring and Lakeside Spring clustered near the water's edge.

Transportation infrastructure follows the volcanic topography, with the Grand Loop Road and South Entrance Road converging at this critical junction. Beyond the geysers, the landscape transitions to high-altitude forests and drainages such as Arnica Cr and Big Thumb Cr. To the southwest, the Continental Divide traverses the terrain, marking the hydrological crest that separates the interior drainage of the park.
