About this map

Flathead National Forest defines this high-elevation landscape along the international border in the mid-1960s. Dominated by prominent peaks such as Mount Hefty and Cleft Rock Mountain, the area is characterized by a network of drainage systems including Yakinikak Creek, Thoma Creek, and Ketchikan Creek. High-point observation is a key feature of the terrain, marked by Thoma Lookout and the Hornet Mountain Lookout positioned above Wedge Canyon.

The map reveals a wilderness area maintained through a series of trails and pack routes rather than developed roads, reflecting the remote character of Flathead County at this time. Water sources like Colts Creek and various Springs are documented alongside notable geological landmarks like Cleft Rock, providing a detailed look at the hydrology and topography south of the United States Canada boundary.
