Hebes Chasma

Today's VIS image crosses the entirety of Hebes Chasma, including the central rise called Hebes Mensa. Located in the center of the image, Hebes Mensa is 7.5 km (4.7 miles) tall and 120 by 43 km (75 by 27 miles) wide. The surrounding Hebes Chasma is is 319 km long (east/west, 198 miles), 130 km wide (north/south, 81miles) and up to 8km (5 miles) deep. Hebes Chasma is an inclosed basin not connected to Valles Marineris. Hebes Mensa is a large deposit of layered materials, and the cliff faces are eroding in a very different way from the Hebes Chasma cliffs.
