2021 Map of West Thumb

About this map

The geothermal activity of Yellowstone National Park dominates this topography, specifically concentrated around the West Thumb settlement. This area is characterized by the high density of hydrothermal features along the shores of Yellowstone Lake West Thumb, ranging from the Fishing Cone located directly at the water's edge to the West Thumb Geyser Basin. The shoreline morphology is defined by Bluff Point and Carrington Island, while the interior terrain includes Duck Lake and the Potts Hot Spring Basin. The southern portion of the map traces the Continental Divide, showing how the land slopes toward various drainages like Solution Cr and Big Thumb Cr. Transportation infrastructure is centered on the intersection of the South Entrance Road and the Grand Loop Road, which provides access to established visitor sites such as Grant Village Road.
