The Caprock Escarpment is a term used in West Texas and Eastern New Mexico to describe the geographical transition point between the level High Plains of the Llano Estacado and the surrounding rolling terrain. In Texas, the escarpment stretches around 200 mi south-southwest from the northeast corner of the Texas Panhandle near the Oklahoma border. The escarpment is especially notable, from north to south, in Briscoe, Floyd, Motley, Crosby, Dickens, Garza, and Borden Counties.
