1966 Map of Lo 7 Hill

About this map

The Grand Hogback dominates this Rio Blanco County landscape, forming a massive geological spine that bisects the terrain. This 1960s survey documents a region defined by its sharp elevation changes and drainage networks, with the eastern slopes falling into the White River National Forest. Water courses like Sheep Creek and Flag Creek cut through the high country, while several named gulches, including Joe Bush Gulch and Segar Gulch, reveal the local nomenclature used by ranchers and outdoorsmen of the era. A solitary Jeep Trail provides the primary access across these ridges, highlighting the area's isolation. The survey also identifies Lo 7 Hill as a prominent local landmark, standing amidst a complex web of seasonal streams such as Miller Creek and the East Fork.
