1996 Map of Lewis Canyon

About this map

The Lewis River carves through the landscape of southern Yellowstone National Park on this 1990s survey, marking a transition between the volcanic Pitchstone Plateau and the Teton National Forest. The map documents the intricate hydrothermal and hydrologic activity of the region, featuring Phantom Fumarole, numerous unnamed Springs, and Hot Springs along the riverbanks. As the river descends through Lewis Canyon, it passes notable landmarks such as Lewis Falls and Moose Falls, eventually meeting the Snake River at the southern park boundary.
