About this map

Yellowstone National Park and the Gallatin National Forest meet in this high-altitude wilderness along the Montana-Wyoming border. This 1986 survey illustrates a landscape defined by deep drainages and high plateaus, where the continental divide influences the flow of seasonal waters. The topography is shaped by prominent features like Jack Straw Basin and the expansive Moose Creek Plateau, which transitions into a series of steep canyons.

Remote water sources such as Big Bear Lake, Frog Pond, and various unnamed springs dot the high country, serving as critical points in a region largely untouched by permanent settlement. The convergence of Gallatin Co and Teton Co highlights the jurisdictional complexity of managing these protected lands. This map is a clear record of the area's natural geography, detailing the intricate system of Meadow Canyon, Echo Canyon, and Black Bear Canyon that carve through the mountain terrain.
