Anticlinal

Anticlinal, Anticline, or Saddle-back, a geological term, applying to an upward fold in rocks by which the beds have been made to dip in opposite directions from a central elevated axis. Becoming fractured under the strain along this axis the rocks may be denuded back from it in two parallel lines of escarpment forming an anticlinal valley or valley of elevation, such as that of the Weald of Surrey, Sussex, and Kent.
