Ganges Chasma (Mars)

This feature is named after an earlier feature.

Ganges Chasma is a deep canyon at the eastern end of the vast Valles Marineris system on Mars, an offshoot of Capri Chasma. Most of the evidence for these discharges and the ensuing collapses is believed to have been washed away. Prior to developing an outlet that joined it to Capri Chasma and the connected outflow channels to its east, Ganges Chasma may at some point in the Noachian period have contained a lake which drained northward through partially subsurface pathways into Shalbatana Vallis.

A chasma is a deep, elongated, steep-sided depression. On Mars they are named after the nearest named albedo feature on the Schiaparelli or Antoniadi maps.
