The Knobs Region is located in the US state of Kentucky. It is a narrow, horseshoe shaped region consisting of hundreds of isolated hills. The region wraps around the bluegrass region in the center of the state. The western end of the Knobs region begins near Louisville, Kentucky and continues southeastward through Bullitt, Hardin, Nelson, Larue, Marion, Taylor, Casey and Lincoln counties before turning northeast and running along the Pottsville Escarpment and the Appalachian Plateau. While stretching for over 100 miles (160 km), the region is never more than 30 miles (48 km) across.
Many of the hills are conical and up to several hundred feet high. Some have harder capstones that form cliffs as the softer stone underneath has worn away.
