2014 Map of Amphitheatre Mountain

About this map

The Chinese Wall of the Lewis and Clark Range forms the defining geological spine of this area, marking the continental divide and the boundary between Flathead National Forest and Lewis & Clark National Forest. This high-altitude landscape is characterized by a network of drainage basins, where the White River flows southward, joined by tributaries like Rooney Cr and Pedro Cr. The terrain is punctuated by prominent summits including Amphitheatre Mtn, Moccasin Butte, and Gladiator Mtn. These peaks and basins, such as Brushy Park, illustrate the complex topography that has historically shaped travel through these mountains. Remote alpine water bodies like My Lake and Diamond Lake sit tucked within high cirques, while gaps like Larch Hill Pass indicate the natural corridors used to navigate the dramatic vertical relief of the front range.
