Heavily cratered highlands and intercrater plains

Heavily cratered highlands and intercrater plains

. The highlands of Mercury exhibit abundant craters, just as the lunar highlands do; but unlike the Moon, intercrater plains occur between large craters. Intercrater plains and heavily cratered terrain are typical of much of Mercury outside the area affected by the formation of the Caloris basin and photographed by Mariner 10 (Courtesy of JPL and NASA.)
