Galaxias Chaos is an area of broken landscape in the
Cebrenia quadrangle of Mars, located at 34.1° N and 213.6° W. It is 234.0 km across and was named after an albedo feature name. Galaxias Chaos may be caused by sublimation of an ice-rich deposit.

Outflow channels
Outflow channels are extremely long, wide swathes of scoured ground on Mars. They extend many hundreds of kilometers in length and are typically greater than one kilometer in width. They are thought to have been carved by huge outburst floods.
