2015 Map of Beach Lake

About this map

Yellowstone National Park terrain defines this section of the Central Plateau, where the hydrology of the Continental Divide manifests in a dense network of high-altitude waterways. The Mary Mountain-Nez Perce Trail provides the primary historical transit corridor across the landscape, connecting the heights of Mary Mtn with the thermal activity at Highland Hot Springs. The area is characterized by its internal basins, most notably the namesake Beach Lake and the nearby Dryad Lake. Multiple drainage systems converge and diverge here, with the headwaters of Alum Cr, Trout Cr, and Spruce Cr carving distinct paths through the wilderness. This 2015 survey details the intricate topography of the Park and Teton county line before the drainages descend toward the park's major river systems.
