About this map

The Tuolumne River and Merced River basins define this early twentieth-century survey of the central Sierra Nevada, showing the region before many modern developments took shape. Based on fieldwork from the 1890s, the map documents a network of high-country ranger stations including Hog Ranch Ranger Sta and Gentry Ranger Sta, alongside early road systems like the Tioga Road and Coulterville Road. The topography illustrates the transition from the foothills near Darrah and Jerseydale to the iconic heights of the high Sierra.

Industrial and tourism footprints are visible at the Colby Min and stopping points such as Crockers and Carl Inn. This 1909 edition, reprinted in 1929, captures the Hetch Hetchy Reservoir in its earlier configuration and identifies the critical Mt Diablo Base Line which guided the state's early cadastral surveys. The document serves as an essential record of early park management and rural settlement patterns in Mariposa and Tuolumne counties.
