|Naming||a classical albedo feature name|
Tractus Fossae is a trough in the Tharsis quadrangle of Mars, located at 26° north latitude and 101.4° west longitude. It is 390 km (240 mi) long and is named after a classical albedo feature name. 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.
