About this map

The Grand Hogback dominates this Colorado landscape, forming a massive geological spine that dictates the drainage patterns of the surrounding Rio Blanco County terrain. Surveyed in the 1960s, the map reveals a remote ranching and forest environment where water management is critical, evidenced by the Highland Ditch traversing the north. To the southeast, the boundary of the White River National Forest indicates the shift from private range land to protected federal timber and watershed areas.

Several prominent watercourses carve through the topography, including Sheep Creek, Miller Creek, and Flag Creek, which generally flow toward the north. Remote access to the higher elevations, such as Lo 7 Hill, is marked by a network of unimproved tracks and a Jeep Trail, reflecting the area's use for livestock grazing and land management. The deep contours of Red Canyon and the East Fork further illustrate the transition from the distinct hogback ridge into the broader plateau and canyon country.
