1901 Map of Mt. Lyell

About this map

Yosemite National Park occupies the core of this late-nineteenth-century study, revealing the high-altitude landscape before the establishment of modern infrastructure. The central corridor is defined by Tuolumne Meadows and the surrounding granite formations of Lambert Dome and Fairview Dome. This era of the park reflects a transition from early pioneer exploration to formal federal protection, with the Sierra Forest Reserve bordering the southern reaches. Topographer R.B. Marshall and his team documented the intricate drainage systems of the Cathedral River and Merced Lake, along with vital high-country landmarks like Soda Springs. The map traces early transit points such as Miller Bridge and Sheep Crossing, providing a clear view of the primitive trail networks that connected the central Sierra Nevada summits with Little Yosemite Valley and the northern lakes.
