The "Tharsis' Montes" (Absolute Natural Colors; credits for the additional process. and color.: Dr Paolo C. Fienga - Lunexit Team)

The alignment of the 3 Shield Volcanoes that make up the Tharsis Montes is clearly evident in this view. The 3 Volcanoes are named Ascraeus Mons, Pavonis Mons and Arsia Mons, going from North to South. The 3 Volcanoes are each somewhat smaller than Olympus Mons, varying from about 350 to 450 Km (approx. 210 to 270 mi) in horizontal extent and each rising about 15 Km (approx. 9 miles) above the surrounding Plains.
The Tharsis Montes are located on the crest of a broad uplift of the Martian Crust so that their Summits are at about the same elevation as the Summit of Olympus Mons.

The "Fractures" to the South/East of Pavonis Mons, are known as "Noctis Labyrinthus"; this Region merges with the enormous Valles Marineris Canyon System to the East. The white patches around the lower Flanks of the Volcanoes are thin Clouds that commonly occur near them.
