2015 Map of Lewis Canyon

About this map

Yellowstone National Park and the adjacent John D Rockefeller Junior Memorial Parkway meet in this 2015 study of the high-elevation terrain between the Lewis River and Snake River. The map highlights the area's hydrothermal activity, documenting specific locations like Phantom Fumarole and Crawfish Creek Hot Springs. The landscape is defined by its complex drainage network, where Polecat Cr, Spirea Cr, and Crawfish Cr flow through deep timber toward the dramatic Lewis Canyon.
