2021 Map of Shoshone Geyser Basin

About this map

Shoshone Geyser Basin sits at the head of the western arm of Shoshone Lake, marking a dense concentration of thermal activity within the backcountry of Yellowstone National Park. This 2021 survey illustrates the complex hydrothermal network of the region, featuring named geothermal landmarks such as Little Giant Geyser, Union Geyser, and the Orion Group. The terrain is defined by the Continental Divide, which separates the headwaters of the Firehole River flowing north from the southern drainages like the Gregg Fork and Ferris Fork. Remote peaks including Trischman Knob and Douglas Knob punctuate the landscape, while the Continental Divide National Scenic Trail provides a primary corridor through this high-altitude wilderness. The map is essential for tracing the historic backcountry trails and the intricate cluster of springs and geysers that define this specific geothermal area.
