Claritas Fossae
Claritas Fossae is a densely-dissected highland terrain on the Tharsis Rise of Mars, located immediately south of the Tharsis Montes. The fossae of the Claritas Fossae region are many superposed swarms of graben.
Context.
Claritas Fossae is a group of troughs in the Phoenicis Lacus and Thaumasia quadrangles of Mars, located at 
31.5 S and 104.1 W. The structure is 2,050.0 km long and was named after a classical albedo feature name.
Geology.
Long narrow depressions on Mars are called fossae.

Context.
The Thaumasia Plateau lies at the heart of the Tharsis Rise, and is framed to the northwest by the Noctis Labyrinthus fracture zone and the Valles Marineris chasmata (particularly, Ius Chasma, Melas Chasma, and Coprates Chasma, from northwest to northeast). Older Noachian basement crust, likely predating the formation of Tharsis, bound the Thaumasia Plateau to the west (Claritas Rise and the Claritas Fossae), the south (Thaumasia highlands), and the east (Coprates Rise and the Nectaris Fossae).
