Discussion from McGrain and Currens (1978)

Todd County is in the Mississippian Plateaus Region of southwestern Kentucky. The Dripping Springs Escarpment, a south-facing cuesta, is parallel to and north of U.S. 68 between Daysville and Fairview and divides the county into two distinct topographic areas.

The southern part of the county is a karst (sinkhole) plain at an elevation of approximately 600 feet; this area has hundreds of solution features such as sinkholes and sinking creeks. The terrain is gently rolling and the relief is slight. The Dripping Springs Escarpment rises 200 feet or more above the sinkhole plain and is the most conspicuous topographic feature in the county. Elevations along the outer edge of the escarpment are from 800 to 850 feet. A knob on the escarpment 2 miles west of Daysville has an elevation of 858 feet, and Keeling Hill, 2 miles east of Fairview, has an elevation of 848 feet.

The area north of the escarpment is a high plateau. This part of the county contains the highest elevations and areas of greatest local relief, and is more highly dissected by normal stream erosion than other parts. Headwater streams occupy narrow valleys and are bordered by rocky cliffs in some places.

The highest point in Todd County is Pilot Rock, adjacent to Ky. 507 at the Todd-Christian County line. The elevation of the top of Pilot Rock is 966 feet. Tucker Ridge, 4 miles north-northeast of Pilot Rock, has an elevation of 880 feet.

The lowest elevation in Todd County is approximately 405 feet, at the point where Pond River leaves the northwestern corner of the county. The elevation of Lake Malone, in the northeastern corner of the county, is 450 feet.

The elevation of Elkton, at the courthouse, is 631 feet. Elevations at other communities are Allegre, 644 feet; Allensville, 581 feet; Claymour, 678 feet; Clifty, 813 feet; Daysville, 645 feet; Fairview, on the Todd-Christian County line, 620 feet; Guthrie, 548 feet; Hermon, 612 feet; Kirkmansville, 500 feet; Sharon Grove, 646 feet; and Trenton, 590 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.
