1909 Map of Yosemite

About this map

Yosemite National Park dominates this survey, conducted originally in the late 19th century and revised just before the onset of the Great War. The landscape shows early mountain infrastructure, including the Stage Station and several remote outposts like Hog Ranch and Hazel Green. The survey emphasizes the region's massive timber and valley geography, marking the Tuolumne Grove Big Trees, Merced Grove Big Trees, and the famous Mariposa Grove Big Trees. At El Portal, the terminus of the Yosemite Valley Railroad is visible near Hennesy. High-altitude features such as Half Dome and Cathedral Rocks are documented alongside early trails like the Pohono Trail and El Capitan Trail, illustrating the park's early years as a managed wilderness under the Sierra National Forest and Stanislaus National Forest.
