Discussion from McGrain and Currens (1978) Adair County is located in the Mississippian Plateaus area of south-central Kentucky. The upland area is moderately to deeply dissected in most parts of the county, but some large, flat ridgetops occur in the central and southeastern parts. Ridgetop elevations generally range from about 900 feet in the northwest to 950 to 1,000 feet in the southeast. Elevations of valley flats are generally 700 to 800 feet. Some sinkholes and springs are present, but karst features do not constitute a prominent part of the landscape. The drainage divide between the Cumberland and Green Rivers crosses southern Adair County. The highest elevations in the county are found there. In the vicinity of Sparksville a ridge on this divide, which parallels Kentucky Highway 61, attains an elevation in excess of 1,120 feet. The lowest elevation is 585 feet where Russell Creek leaves the county. Maximum local reliefs occur at bluffs along the entrenched streams, where differences in elevation range from 100 to 260 feet. The highest bluffs border Green River Lake in northwestern Adair County. Other elevations of special interest are Columbia, at the courthouse, 750 feet; Breeding, 974 feet; Cane Valley, 785 feet; Gradyville, 712 feet; Knifley, 721 feet; and Green River Lake (normal pool level), 713 feet. The 7.5-minute topographic quadrangle maps that cover the county are
shown, by name and by index code (Kentucky Natural Resources and Environmental
Protection Cabinet) on the index
