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.[1] Some of the first gullies on Mars were found in Gorgonum Chaos.[2] It is generally believed that it once contained a lake.[3][4] 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.[5]
