About this map

Boundary Ridge forms the backbone of this high-elevation landscape, where the tri-state intersections of Idaho, Wyoming, and Utah converge across a complex network of drainages and plateaus. Surveyed in 1970, the map illustrates the remote ranching and grazing character of the Bear Lake Plateau, an area defined more by its water sources and named hollows than by permanent settlements. The presence of Dairy Hollow, Taylor Meadow, and various Spring locations suggests a landscape deeply tied to seasonal livestock movement and mountain resource extraction.

Remote infrastructure is sparse, limited primarily to a network of Jeep Trails and scattered Gravel Pits. Notable landmarks like Red Mtn and the winding Poison Creek provide essential orientation for researchers tracing land use in this corner of the Rockies. The jurisdictional complexity of the area is highlighted by the proximity of Bear Lake Co, Lincoln Co, and Rich Co boundaries, making this a critical document for understanding the territorial divisions of the high country.
