1911 Map of Gallatin

About this map

Fort Yellowstone stands as a primary outpost on this early 20th-century topographic record, marking the military administration of the region before the creation of the National Park Service. The map details a complex landscape of thermal activity and early tourism infrastructure, centered around the Mammoth Hot Springs and the Norris Geyser Basin. Travel routes of the era are clearly delineated, including the Snow Pass Trail and the Cooke Road, alongside early hotel developments such as the Fountain Hotel and Mammoth Hotel. Beyond the established geothermal hubs, the survey tracks the high-altitude terrain of the Gallatin Range and the Madison Plateau, documenting the sources of the Gallatin River and Madison River. Notable landmarks like Liberty Cap and the Artist Paintpots are recorded alongside vital river crossings like Chittenden Bridge, illustrating how early visitors navigated this hydrothermal wilderness.
