1989 Map of Mount Hornaday

About this map

Yellowstone National Park dominates this 1989 provisional survey, showing the high-altitude landscape where the Lamar River meets its major tributaries. The northern wilderness of Park County is defined here by the confluence of the Slough Creek drainage and the steep elevations of Mount Hornaday and Bison Peak. The map provides a detailed look at the park’s infrastructure during the late 1980s, including the Lamar Ranger Station and the winding path of the Northeast Entrance Road.
