About this map

Yellowstone National Park reveals its geothermal and high-country character in this mid-1980s topographic record. The landscape is anchored by the Central Plateau and the prominent ridge of Mary Mountain, a region defined by its thermal activity and complex drainage systems. Named thermal features like Highland Hot Springs and other Hot Springs are documented alongside the remote Beach Lake and Dryad Lake.

The presence of an established Pack Trail winding through the terrain suggests the historical and continued reliance on traditional backcountry routes for accessing the park's interior. This map traces the headwaters and courses of several significant waterways, including Alum Creek, Trout Creek, and Arnica Creek, illustrating the intricate hydrologic patterns of the plateau before modern climate shifts or significant landscape changes might have altered these remote drainage basins.
