Crater walls are the interior sides of a crater rim.


Circumvallation (Elger 1895, obsolete) terraced zone (if in a complex crater)


 Simple craters have smooth walls; consisting of a single slope segment from crater floor to crater rim. Sometimes simple crater walls can have a two-tiered profile which includes a slightly shallower segment formed due to the collection of debris at the foot of the main wall slope.  complex crater walls are commonly broken up into a series of slumps or terraces ( terraced crater wall (mass wasting)) which step down into the crater (Collins 2002, p. 20).


Average interior slopes (S) can be determined using the equation developed by Wood and Andersson ( 1978) for fresh lunar simple craters (Fig. 1):
