NASA's Mars Global Surveyor shows rugged terrain in northern Arabia Terra. The circular features are the remains of old meteor impact craters. The martian bedrock has craters of all sizes and states of erosion interbedded with its layered materials.

This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows rugged terrain in northern Arabia Terra. The circular features are the remains of old meteor impact craters -- either the eroded remnants of the interiors of craters, or the remains of craters that were filled by layered material. The martian bedrock has craters of all sizes and states of erosion interbedded with its layered materials.
