About this map

Mammoth Hot Springs serves as the focal point of this northern Yellowstone landscape in the mid-1980s. The map illustrates the concentration of park infrastructure near Mammoth, including a Heliport, Radio Tower, and administrative buildings clustered near Capitol Hill. The complex thermal geography is detailed through labels for the Main Terrace and Highland Terrace, which sit adjacent to the dramatic drop of the Gardner River canyon.

To the south, the terrain rises sharply toward Bunsen Peak and the massive Sheepeater Cliffs. This survey documents the network of trails and roads, including the One Way route near Swan Lake Flat, that provide access to natural landmarks like The Hoodoos and the narrow passage at Golden Gate. From the broad valley of Gardners Hole to the heights of Mount Everts, the map records a high-mountain environment where geothermal activity and glacial landforms meet.
