About this map

Mammoth Hot Springs serves as the focal point of this northern Yellowstone survey, where geothermal activity and administrative development intersect. The map documents the intricate layout of the Main Terrace and Highland Terrace formations, situated just above the Mammoth settlement. This area, which includes Capitol Hill and a Heliport, reflects the mid-1980s infrastructure supporting park management and tourism.

Beyond the developed center, the landscape is defined by dramatic elevation changes and hydrothermal features. The survey traces the Gardner River as it carves through Gardner Canyon, while landmarks like The Hoodoos and the Sheepeater Cliffs suggest the complex volcanic and glacial history of the region. From the elevations of Bunsen Peak to the waters of Swan Lake in Gardners Hole, the map provides a precise record of the geological and human footprint at this specific moment in the park's history.
