About this work
Today's VIS image shows part of Ius Chasma and one of its mega gullies (bottom of image). Ius Chasma is unique from the other chasmata of Valles Marineris in possessing mega gullies on both sides of the chasma. The largest mega gullies are located in Sinai Planum, dissecting those plains and emptying into the canyon. Mega gullies are thought to be sapping channels caused by groundwater flow and erosion.
