Gorgonum Chaos [SEP] located on astronomical body
Gorgonum Chaos
Gorgonum Chaos is a set of canyons in the Phaethontis quadrangle of Mars. It is located at 
37.5° south latitude and 170.9° west longitude. Its name comes from an albedo feature at 24S, 154W. Some of the first gullies on Mars were found in Gorgonum Chaos. It is generally believed that it once contained a lake. Other nearby features are Sirenum Fossae, Maadim Vallis, Ariadnes Colles, and Atlantis Chaos. Some of the surfaces in the region are formed from the Electris deposits.

Terra Sirenum is the location of many Martian gullies that may be due to recent flowing water. Some are found in the Gorgonum Chaos and in many craters near the large craters Copernicus and Newton. Gullies occur on steep slopes, especially on the walls of craters. Gullies are believed to be relatively young because they have few, if any craters. Moreover, they lie on
