About this map

Madison Junction sits at the vital confluence where the Gibbon River and Firehole River meet to form the headwaters of the Madison River. This 2017 survey details the complex hydrothermal landscape of Yellowstone National Park, showcasing the thermal activity of the Gibbon Geyser Basin and the higher-elevation Monument Geyser Basin. The terrain is defined by dramatic elevation changes, from the sheer heights of National Park Mtn and Purple Mtn down to the steep walls of Gibbon Canyon.

Transport through this geothermal corridor follows the Grand Loop Road, which provides access to notable landmarks like Gibbon Falls and the secluded Secret Valley Hot Springs. For those traveling on foot, the Purple Mountain Trail offers a route into the backcountry overlooking the valley. This map effectively captures the intersection of early park infrastructure and the volatile geological features that define the region, including named vents like Jet Geyser and Monument Geyser.
