Ophir and Candor Chasmata

Today's VIS image shows parts of Ophir Chasma (top of image) and Candor Chasma (bottom of image). Both are part of Valles Marineris. Candor Chasma is approximately 810 km long (503 miles) and is divided into two regions - eastern and western Candor. This image is of western Candor Chasma. The floor of Candor Chasma includes a variety of landforms, including layered deposits, dunes, landslide deposits and steep sided cliffs and mesas. Many forms of erosion have shaped Candor Chasma. There is evidence of wind and water erosion, as well as significant gravity driven mass wasting (landslides). Ophir Chasma is approximately 317km long (197 miles). This image shows the western end of Ophir Chasma. A landslide is visible in Ophir Chasma.
