Ariadnes Colles is a region of colles (hills) in the northeast of Eridania quadrangle of Mars, also it is in the eastern area of Terra Cimmeria. It is located around 34.2 ° south latitude, and 172.78° east longitude. The region is 188 kilometers (117 mi) across from east to west and the highest elevation is about 300 meters above the lowest point. Unlike another chaotic terrain, Iani Chaos which is located in the middle of the planet, the feature is not a scalloped terrain.[1]
The feature was named by the IAU in 1982, and was named after an albedo feature, the only feature named after the Ariadnes Depressio which means the "lowland of Ariadne". a Greek heroine.[2]
Description[edit]

Map of Eridania Lake, it included the area which later became Ariadne Colles
Just next to is Karūn Valles located to the southeast, further south are one of the two troughs of Sirenum Fossae and further east is Caralis Chaos. Also further north is Ma'adim Vallis.
Alongside nearby the chaotic terrains of Atlantis Chaos, Caralis Chaos and Simois Colles, it also contains an ancient dry lakebed (possibly part of Eridania Lake),[3] as well as structures that appear to be recently formed gullies, which suggests the possibility of long-term hydrothermal activity.[4] As Eridania Lake dried out in the late Noachian epoch, it divided into a series of smaller lakes, but the area would have smaller lakes and was one of the last three parts that were dried out.
