Ganges Chasma is a deep canyon at the eastern end of the vast Valles Marineris system on Mars an offshoot of Capri Chasma. It is named after the River Ganges in South Asia. Ganges Chasma is thought to have formed through a series of catastrophic discharges of water and CO2 from chaos terrains such as that preserved in Ganges Chaos at its southern margin. Most of the evidence for these discharges and the ensuing collapses is believed to have been washed away.
