Hydraotes Chaos (Mars)

This feature is named after an earlier feature.

More information and more examples of chaos regions can be found at Martian chaos terrain. The area contains small conical edifices, called Hydraotes Colles, which were interpreted as the Martian equivalent of terrestrial cinder cones formed by volcanic activity. (wikipedia entry)

A chaos is a distinctive area of broken or jumbled terrain. On Mars they are named after the nearest named albedo feature on the Schiaparelli or Antoniadi maps.
