Cliff in Terby Crater

July 29, 2003
Terby Crater was once filled with layered, sedimentary rock. Over time, these materials have been eroded to form a dazzling array of cliffs and layered outcrops. This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) picture shows a layered cliff facing toward the northwest (toward upper left). Dark debris has slid down the west-facing slopes of the cliff. A visitor to Terby Crater would be greeted by vistas reminiscent of some of the national parks in the southwestern United States. This March 2003 picture is located near 27.7°S, 285.5°W; it is illuminated by sunlight from the upper left. The picture covers an area 3 km (1.9 mi) across.
