Mega-Gullies

Today's VIS image shows part a section of a mega gully. Located on the plains of Sinai Planum, it is just one of a number of huge channels that line the cliff face of Ius Chasma. The linear sides of the channel indicate that the formation of these features included tectonic activity. Ius Chasma is on the western end of Valles Marineris.
