About this map

Yellowstone Lake dominates the northern expanse of this 1885 survey, its intricate shoreline defined by the South Arm and South East Arm reaching into the high wilderness. The terrain is a complex network of high-altitude drainage systems where the Continental Divide winds between Chicken Ridge and the Two Ocean Plateau. This era of the park's history is marked by the presence of isolated outposts like Hawks Rest near the southeastern boundary, situated along the upper reaches of the Yellowstone River and Thorofare Creek.

Notable geological and water features reveal the wild character of the late 19th-century park interior, including Brimstone Basin and the remote Mariposa Lake. The surveyor’s attention to detail captures the unique hydrology of Two Ocean Pass, where waters part toward different oceans. To the east, the dramatic peaks of the Absaroka Range such as The Trident form a natural barrier at the edge of the Yellowstone Forest Reserve.
