1982 Map of Irvine Lookout Tower

About this map

The Hog Heaven Range dominates this portion of the Flathead Indian Reservation, providing a look at the high-elevation landscape of the early 1980s. Strategically positioned for forest surveillance, the Irvine Lookout Tower stands as the primary landmark overlooking a network of drainages including Cromwell Creek and Earth Creek. The map documents the persistent agricultural and ranching footprint in the region, specifically marking the Bower Ranch and Pablo Ranch. These ranching outposts, connected by a Jeep Trail and unimproved routes, illustrate the intersection of private land use and tribal reservation boundaries. The presence of a Gravel Pit along the Big Draw suggests local infrastructure maintenance during this era, while the overall terrain remains characterized by steep draws like Deep Draw and numerous unnamed springs.
