1907 Map of Canyon

About this map

Yellowstone National Park reveals its geothermal and geological complexity in this 1907 survey, conducted years before modern tourist infrastructure reshaped the park. The map centers on the Grand Canyon of the Lamar River and the high elevations of the Mirror Plateau. Noteworthy early landmarks like Yanceys and a remote Hotel near Tower Falls illustrate the limited frontier-style accommodations available to early explorers. The landscape is defined by its thermal activity, documented through numerous labels for Hot Springs, the Mushpots, and the Mud Geyser. Geologists and researchers can trace the original nomenclature of the Fossil Forest and the Sulphur Hills, alongside historical crossings like Baronett Bridge. The sheet extends south to the northern reaches of Yellowstone Lake, capturing the shoreline near Bridge Bay and Stevenson Island.
