Appalachian Plateau Province
  An imposing escarpment, known as the Allegheny Front, divides the Ridge and Valley Province from the Appalachian Plateau Province. It includes Backbone Mountain, Maryland's highest point at 3,360 feet above sea level. Slopes in the Appalachian Plateau are often steep and deeply carved by winding streams. This province has mountainous soils composed of clay and clay loams. In higher elevations of the Appalachian Plateau, the climate becomes similar to that of the northern states and Canada.
