Ridge and Valley Province
  The Ridge and Valley Province is where the parallel ridges and valleys of the Appalachian Mountains create an alternating pattern. This province has mountainous soils composed of clay and clay loams, as well as sandy and stony loams. Often, the soils are shallow, and shale barrens may be found. The climate is dry. Most of the precipitation from the west is blocked by the Allegheny Mountain range, and precipitation from the east is blocked by the Blue Ridge Mountains. Prickly pear, a cactus, thrives in parts of this province.
