Volcanic_Features-Collapse_Pits_and_Chains-AM-PIA16647-PCF-LXTT-IPF.jpgCollapse Features on the Northern Flank of Ascraeus Mons (Absolute Natural Colors; credits for the additional process. and color.: Dr Paolo C. Fienga/Lunar Explorer Italia/Italian Planetary Foundation)61 visiteThis image was taken by the NASA - Mars Odyssey Orbiter, this time during its 47952nd Orbit, and it shows us a small fraction of the unbelievably compllicated Network of Collapse Features (Pits, Pit-Chains, Channels and Fissures) which are located on the Northern Flank of the Martian Volcano known as Ascreaus Mons (a large Shield Volcano located in the Tharsis Region of the Red Planet). Ascraeus Mons is the Northernmost and tallest of the 3 (three) Shield Volcanoes collectively known as the Tharsis Montes,being the other two huge Volcanoes known as Pavonis and Arsia Mons (if you wish to have an orbital vision of all these three fascinating Volcanoes, as well as a portion of the Noctis Labyrinthus Region of Mars, please go to Archive and refer to the APOD of February, 14th, 2012). Out of curiosity, Ascraeus Mons' location corresponds to the so-called "Classical Albedo Feature" which was known as Ascraeus Lacus.
Ascraeus Mons was actually discovered by the NASA - Mariner 9 Spacecraft in 1971. This enormous Volcano, however, was originally just called "North Spot", since it was the Northernmost of the only 4 (four) "Spots" (---> Reliefs) visible on the whole Surface of Mars which, at that time (and due to a Global Dust Storm), looked completely featureless from the orbit. As the Dust cleared, the abovementioned "Spots" were revealed to be extremely tall Shield Volcanoes whose Summits stood above the Dust-flooded, Lower Atmosphere. The Volcano's name officially became Ascraeus Mons in 1973.

Fienga/Lunar Explorer Italia/Italian Planetary Foundation)60 visiteThis image, taken by the NASA - Mars Odyssey Orbiter during its 48003rd Orbit, shows us a VERY small (but still extremely interesting, as you can see by yourself) portion of the steep Escarpment existing between the Main Edifice of the Great Martian Volcano known as Olympus Mons and the surrounding Volcanic Plains (remember that an Escarpment is a - usually - steep Slope or a long Cliff that occurs from Erosion or Faulting and separates 2 (two) - relatively levelled/flat - areas/terrains which are situated at different elevations with regard to a certain, and given, Datum - such as that Point, Place or Region of a Celestial Body that is conventionally considered to be situated at Zero Altitude (the Sea Level, for instance, and as far as the Planet Earth is concerned).

Volcanic_Features-Fractures-AM-PIA16499-PCF-LXTT-IPF.jpgFractures near and around Alba Mons (Absolute Natural Colors; credits for the additional process. and color.: Dr Paolo C. Fienga - Lunar Explorer Italia - Italian Planetary Foundation)78 visiteIn addition to its great size (consider that its Lava Flow Fields extend from over than 1400 Km from the Summit) and relatively low relief (the Summit of the Volcano reaches an elevation of "only" 6,8 Km as to the surrounding Lava Plains), Alba Mons possesses a number of other very distinguishing features. For instance, the central portion of the Volcano is surrounded by an incomplete Ring of Faults (---> Graben) and Fractures (like the ones that we see in today's APOD), called Alba Fossae (the ones located on the Volcano's Western Flank), and Tantalus Fossae (which are found on its Eastern Flank).
Alba Mons also has very long and well preserved Lava Flows that form a Radiating Pattern, starting from its Central Region. The enormous lengths of some individual Flow (something more than 300 Km - such as about 190 miles) implies that the Lavas which formed them were not only very fluid (---> meaning that they possessed very Low Viscosity) at the time of the eruption, but that they also must have been erupted in an extremely high volume (---> quantity). Many of the Flows have distinctive morphologies, consisting of long, sinuous Ridges with discontinuous Central Lava Channels. The low areas between the Ridges (and particularly along the Alba's Northern Flank) show a branching pattern of shallow Gullies and Channels (---> Valley Networks) that likely formed by water runoff. Last, but not least, Alba Mons shows, among other things, some of the oldest, and most extensively exposed Deposits that can be found in the whole Volcanic District of Tharsis.
