About this map

Flathead National Forest defines this high-elevation wilderness along the international boundary between Canada and the United States. Surveyed in the mid-1960s, the terrain is dominated by a series of prominent peaks and deep drainage basins, including Mount Hefty and the ridgeline of Cleft Rock Mountain. A network of pack trails serves as the primary infrastructure for the area, connecting remote observation points like the Thoma Lookout and the Hornet Mountain Lookout.

The presence of Tuchuck Campground near the confluence of Yakinikak Creek and smaller tributaries suggests the area's role in forest management and backcountry recreation during this era. Geologic and natural features such as a Cave and various Springs are documented alongside the steep descent of Wedge Canyon. This map captures a landscape where transportation was dictated by topography, relying on routes like the Pack Trail to navigate the drainages of Thoma Creek and Seemo Creek.
