About this map

The Hog Heaven Range dominates the northern half of this mid-1960s survey, where elevations rise steeply to the Hog Heaven Lookout Tower. Positioned within the Flathead Indian Reservation, the landscape is defined by the sharp divide of the Flathead Co Lake Co line and a series of dramatic drainages including Big Draw and Deep Draw. The southern portion of the sheet transitions into the rugged drainage of White Earth Creek and the southern slopes below Irvine Lookout Tower.

Human activity is concentrated in localized pockets such as the Pablo Ranch and Bower Ranch, reflecting a landscape geared toward ranching and resource extraction, the latter evidenced by a Gravel Pit near the central highway. The presence of multiple springs, like those feeding Cromwell Creek, underscores the critical importance of water sources for these upland operations in Western Montana before more extensive modern development reached the area.
