From the authors notes:

The LO7 Hill 7.5-minute quadrangle is located in Rio Blanco County, Colorado along the Grand Hogback south of the White River Valley. The Town of Meeker lies 2½ miles to the north, inside (east of) the Grand Hogback on State Highway 13. Meeker is the county seat of Rio Blanco County. The most striking features in the LO7 Hill quadrangle are the uplands along the southwest margin, the Grand Hogback in the center, and highlands in east that includes LO7 Hill. South- to north- flowing Sheep Creek and Flag Creek are the major drainage basins. The highest elevation is 8,831 feet, in the White River National Forest above Hay Flat Trail in the southeast corner of the quadrangle. The lowest elevation (6,203 feet) occurs on the floor of an unnamed, ephemeral creek channel in the northwest corner of the quadrangle that flows to the White River Valley.
