Discussion from McGrain and Currens (1978)

Jackson County is in the coal field area of southeastern Kentucky. It is an upland area characterized by deeply entrenched streams and cliff-lined valleys. Elevations in excess of 1000 feet prevail over most of the county. Elevations less than 1000 feet are found only along a few of the larger streams.

The highest elevations are in the northwestern part of the county where several ridges and hills attain elevations of 1600 feet or more. The highest point, 1633 feet, is on a ridge near the Jackson-Rockcastle County line about 1 1/4 miles south of Morrill. Maximum local reliefs in this part of the county may exceed 600 feet. A few sinkholes are found in the bottoms of deeper valleys in this part of the county, modifying the normal valley profiles and drainage patterns.

Elevations decrease and the terrain is more subdued in the southeastern part of the county. Ridgetop elevations rarely exceed 1200 to 1300 feet, maximum local reliefs of 300 feet are common, and cliffs are less abundant.

The lowest elevation in the county is approximately 650 feet, the point where Station Camp Creek flows northward out of the northeast corner of the county. In the southwest corner, Rockcastle River leaves the county at an elevation of approximately 870 feet.

The elevation of McKee, the county seat, is 1030 feet. Other elevations are Annville, 1094 feet; Morrill, 1500 feet; Parrott, 1280 feet; Sandgap, 1490 feet; and Tyner, 1182 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 map.
