Abstract
Crater density determinations for parts of the surfaces of several of Saturn's icy satellites including Rhea, Dione, Mimas, Tethys and 1980S3 reveal significant variations. These data, combined with observations of surface morphology, indicate that each satellite has undergone extensive post heavy bombardment geological evolution.
