1958 Map of Mammoth

The landscape is defined by geothermal and geological landmarks, from the thermal activity at Roaring Mountain and Amphitheater Springs to the sheer faces of Obsidian Cliff and the Sheepeater Cliffs. Local relief is represented by the Washburn Range and prominent peaks like Mount Everts and Bunsen Peak. Remote park operations are visible through scattered Patrol Cabins and utility features like a Gravel Pit, providing a look at the management of this wild terrain before later modernizations.
