Summit accordance

A summit accordance exists when hill and mountaintops tops, and eventually also plateaux, have such disposition that they form a geometric plane that may be either horizontal or tilted. Summit accordances can be the vestiges of former continuous erosion surfaces that were uplifted and eroded.[1] Other proposed explanations include:[2]

  • the possibility that erosion becomes more effective at height, tearing down mountains that stand out
  • that isostasy regulates the height of individual mountain masses meaning that small mountains might be uplifted and large mountains dragged down
  • that landscape dissection by uniformly spaced streams eventually reach a state in which summits attain similar heights
  • that summit accordance is derivative of structural planes exposed by erosion
