Ganges Chasma is a deepcanyon at the eastern end of the vastValles Marineris system onMars, an offshoot ofCapri Chasma, and is in theCoprates quadrangle. It is named after theRiver 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.^[1] Most of the evidence for these discharges and the ensuing collapses is believed to have been washed away.^[1] Prior to developing an outlet that joined it to Capri Chasma and the connectedoutflow channels to its east, Ganges Chasma may at some point in theNoachian period have contained a lake which drained northward through partially subsurface pathways intoShalbatana Vallis.^[2]
