2015 Map of Shoshone Geyser Basin

About this map

Shoshone Geyser Basin serves as a focal point for this wilderness survey, highlighting the active geothermal features within Yellowstone National Park. The map documents a complex hydrological network where the Firehole River originates near Madison Lake, while the Continental Divide winds through the high country, separating the drainage of Shoshone Lake from the westward-flowing waters. Researchers can identify specific thermal vents including Little Giant Geyser, Shield Geyser, and the Orion Group. The terrain is further defined by the Cement Hills and Douglas Knob, with backcountry access marked by the Continental Divide National Scenic Trail and the Bechler River Trail. This detailed recording of springs and geysers like Washtub Spring and Boiling Spring provides an essential record of the park's hydrothermal activity in the early 21st century.
