About this map

Yellowstone National Park encompasses a landscape of geothermal activity and deep water in this 1980s study of the Yellowstone Lake shoreline. The northern reach of the lake meets the Yellowstone River at Fishing Bridge, a critical junction for travel through the interior of the park. Geothermal features are densely clustered in the north, where Mud Volcano, Black Dragons Caldron, and various Mud Geysers define the hydrothermal character of the terrain.

The presence of the Lake settlement and Lake Junction near the shoreline reflects the established infrastructure of the era, complete with a Campground and Boat Ramps at Bridge Bay. Further inland, the map captures the transition from the broad flats of Hayden Valley to the rising elevations of Elephant Back Mountain, illustrating the park's diverse topography before more modern development altered these visitor hubs.
