This Viking 1 Orbiter image shows Belz Crater in Chryse Planitia, Mars. Belz is a typical rampart crater, showing a raised ridge or rampart around the inner ejecta layer. These ramparts may be the result of ejecta being emplaced as a debris flow rather than ballistically as is the case for craters on the Moon. North is at 1:30 in this image. The frame is about 50 km wide.
