About this map

The Bob Marshall Wilderness forms the core of this landscape, where the Continental Divide winds through the high peaks of the Trilobite Range. This 1994 revision illustrates the intersection of several significant conservation areas, including the Sun River Game Preserve and the Flathead National Forest, defined by the physical boundary of the Flathead Co Lewis and Clark Co line.

Major drainages like the Mid Fk Flathead River and Bowl Creek carve deep valleys between massive formations such as Pentagon Mountain and Clack Mountain. For those studying the backcountry infrastructure of the late 20th century, the map tracks the Continental Divide National Scenic Trail and the remote Spotted Bear Rocky Mountain Rd, providing a clear record of access points at Switchback Pass and high-altitude water bodies like Lake Levale and Dean Lake.
