Tractus Catena
Tractus Catena is a set of pits in the Arcadia quadrangle of Mars. Its location is centered at . It is long and was named after a classical albedo feature name. The term "Catena" refers to a chain of craters.
The line of pits that make up Tractus Catena make it related to fossa which are common on Mars.
Dark slope streaks are visible in one of the pictures below. Such streaks are common on Mars. They occur on steep slopes of craters, troughs, and
Crater chain
A crater chain is a line of craters along the surface of an astronomical body. The descriptor term for crater chains is catena, plural catenae (Latin for "chain"), as specified by the International Astronomical Union's rules on planetary nomenclature.
Many examples of such chains are thought to have been formed by the impact of a body that was broken up by tidal forces into a string of smaller objects following roughly the same orbit. An example of such a tidally disrupted body that was observed prior
