1901 Map of Lake

About this map

Yellowstone Lake dominates the upper half of this 1901 topographic sheet, revealing the intricate shorelines of the South Arm, South East Arm, and Flat Mountain Arm. Surveyed in 1885, the map captures the wilderness of the Yellowstone National Park and the adjacent Yellowstone Park Forest Reserve before modern infrastructure developed. To the east, the Absaroka Range presents a formidable series of summits including Mt. Stevenson and Mt. Schurz, while the Continental Divide winds across the Two Ocean Plateau in the south. The presence of Hawks Rest near the southern boundary line serves as a rare point of human reference in a landscape otherwise defined by geographic giants like Flat Mountain and Chicken Ridge. The map identifies various geothermal and hydrologic features, such as Hot Sprs. near Cub Creek and the isolated waters of Delusion Lake.
