vo1_mg01n104[1]-PCF-LXTT-01.jpgThe "Tharsis' Montes" (Absolute Natural Colors; credits for the additional process. and color.: Dr Paolo C. Fienga - Lunexit Team)156 visiteThe 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.MareKromiumNov 07, 2011

From NASA SP-444, 1980) 120 visiteThis painting, based on a mosaic of black-and-white Viking Orbiter images of Olympus Mons, shows the volcano's flanks and complex caldera protruding above thin clouds of water ice.

Volcanoes-Olympus_Mons.jpgImage n. 641A52 - Olympus (Enhanced Absolute Natural Colors; credits for the additional process. and color.: Dr Paolo C. Fienga - Lunexit Team) 211 visiteThis image shows the Volcano Olympus Mons. With a diameter of more than 600 Km (approx. the size of Arizona) and a height of nearly 25 Km above the surrounding Plains, Olympus it is the tallest volcano known to exist in the Solar System. When clouds are present, it is sometimes even visible above the clouds.
The relative ages of the Surface in various parts of Mars can be estimated from the number of Impact Craters present in a given area, with young regions having fewer craters than old regions. Only two Craters are visible here, indicating that Olympus Mons is young, probably the youngest Volcanic Feature on Mars. By some estimates, the most recent large volcanic eruption at Olympus Mons occurred only 25 million years ago. The oldest activity at Olympus Mons could be much older than this and would have been buried by younger Lava Flows.
The Caldera of Olympus Mons is the depression near the top center of the image. The Caldera is about 65 × 80 Km across (approx. the size of Rhode Island) and occurs near the maximum elevation of the Volcano. It formed when the Magma within the Volcano either erupted out of Vents located on the side, or temporarily drained deeper into the Planet. In either case, the removal of this Magma allowed part of the overlying Surface to collapse, producing a topographic depression that is termed as "Caldera". The overlapping series of structures in the Olympus Mons Caldera demonstrates that this Magma withdrawal occurred a number of different times.
Similar Calderas are seen on other Volcanos, both on Mars and on Earth.MareKromiumNov 07, 2011

vo1_00437-01.jpgMosaic P-18114 - Noctis Labyrinthus at Dawn (Absolute Natural Colors; credits for the additional process. and color.: Dr Paolo C. Fienga - Lunexit Team)204 visiteThis image shows Early Morning Fog in the Noctis Labyrinthus Region of Mars, at the Westernmost End of the Valles Marineris Canyon System. This Fog, which is probably composed of Water Ice, is confined primarily to the low-lying Troughs, but occasionally extends over the adjacent Plateau. The Region shown here is about 300 Km across.MareKromiumNov 07, 2011
