A region of planetary surface consisting of closely packed, overlapping craters



Heavily cratered terrain, or sometimes just “cratered terrain,” has been used as a terrain mapping unit on various icy satellites, for example, for regions on Dione (Moore 1984) and most of Callisto (Schenk 1995) or Rhea (Moore et al. 1985; Fig. 1). As defined for Mercury (Trask and Guest 1975), heavily cratered terrain consists of both arrays of closely packed overlapping craters and isolated craters exceeding 30 km diameter that are sufficiently old for neither their ejecta blankets nor their associated fields of secondary impact craters to still be visible.
