Tractus Fossae (Mars)

This feature is named after an earlier feature.

The name "Fossae" is used to indicate large troughs when using geographical terminology related to Mars. Troughs, sometimes also called a graben, form when the crust is stretched until it breaks, which forms two breaks with a middle section moving down, leaving steep cliffs along the sides. Sometimes, a line of pits form as materials collapse into a void that forms from the stretching. (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.
