About this map

The Chinese Wall stands as a massive geologic landmark along the eastern edge of this landscape, marking the high-elevation boundary where Lewis & Clark National Forest meets the Flathead National Forest. This remote section of the Lewis and Clark Range is defined by a complex drainage system fed by the White River, which snakes through the central valley. The topography is characterized by dramatic ridges like the Flathead Alps and significant peaks including Tillson Peak, Fault Peak, and the namesake Haystack Mtn.

Evidence of early mountaineering and forest management is seen in the Haystack Mtn Trail and the Indian-Upper Switchback, which provide access to White River Pass. The presence of several named shale formations, such as Tillson Shale, indicates the distinct geological composition of these summits. Small, isolated alpine features like Prisoner Lake and several forks of Lime Creek and Brownstone Creek illustrate the untouched nature of this high-altitude wilderness during the early 21st century.
