Claritas Fossae (Mars)

This feature is named after an earlier feature.

Long narrow depressions on Mars are called fossae. Troughs form when the crust is stretched until it breaks. The stretching can be due to the large weight of a nearby volcano. (wikipedia entry)

A fossa is a long, narrow, shallow depression. On Mars they are named after the nearest named albedo feature on the Schiaparelli or Antoniadi maps.
