North_Polar_Features-North_Polar_Margin-Chasma_Boreale-PIA07052-PCF-LXTT.jpgNorth Polar "Scarp" (Absolute Natural Colors; credits for the additional process. and color.: Dr Paolo C. Fienga - Lunexit Team)254 visiteCaption NASA:"This 1,6 meters (~5 feet) per pixel Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows a typical North Polar Scarp and associated dark windblown Sand Dunes. Layers of material -- possibly Dust and Ice -- are exposed by the Scarp. The small white patches in the image are remnants of seasonal Frost. When this North Polar image was acquired in late September 2004, most of the Polar Frost had sublimed away. This image is located near 85,1 North Lat. and 210,8West Longitude. The scene covers an area of approximately 3 Km (about 1,9 mi) across, and is illuminated by sunlight from the lower left.MareKromium

Volcanic_Regions-Rocky_Outcrops-MGS-01.jpgStreamlined Rocky Outcrops near Olympus Mons (Enhanced Absolute Natural Colors; credits for the additional process. and color.: Dr Paolo C. Fienga - Lunar Explorer Italia) 251 visiteCaption NASA originale:"This MGS-MOC image shows wind-eroded "Streamlined" Rocky Outcrops overlying Lava Flow Surfaces located to the West of Olympus Mons. Outcrops with this appearance are also called Yardangs.
Yardangs typically form in Sedimentary Rock or Volcanic Ash that contains some amount of Sand. The weathering of the Rock due to the Aeolian action cause the release of sand-sized particles from the Outcrops and, in time, such a form of erosion slowly shape the rock into the classic, inverted boat hull-like shapes of Yardangs".
Location near: 13,2° North Lat. and 160,1° West Long.

Flow_Features-Zephyria_Planum-PIA03066.jpgFlow Features in Zephyria Planum (Absolute Natural Colors; credits for the additional process. and color.: Dr Paolo C. Fienga - Lunexit Team) 250 visiteOriginal caption:"This MGS-MOC image shows the broken, platy texture of Flow Surfaces in the Zephyria Region of Mars. Some investigators have suggested that these materials represent the remains of an ice-covered lake; others suggest that these are the Surfaces of hardened Lava that - when it was erupting - was very hot and fluid. Although not illustrated here, a key piece of evidence against the ice-covered lake hypothesis is that there are some small Craters formed on these Surfaces, and some of them have Boulders in their Ejecta Blanket. The Boulders indicate that the material is rock-solid".
