1895 Map of Lake

About this map

Yellowstone Lake dominates this late-nineteenth-century study of the park’s southeastern reaches, a landscape defined by glacial waters and the high peaks of the Absaroka Range. The map illustrates the complex hydrology of the Continental Divide, most famously at Two Ocean Pass, where waters part toward both the Atlantic and Pacific slopes. The intricate shoreline of the lake is documented in detail, from the Flat Mountain Arm to the South East Arm, featuring landmarks like Frank Island and the isolated Molly Island. To the east, the terrain rises sharply toward massive summits including Mt Stevenson and Mt Doane. This survey reflects an era of early park administration, showing the boundary line between the Yellowstone National Park and the Yellowstone Park Forest Reservation, a precursor to the modern national forest system.
