PSP_001700_2505-PCF-LXTT-IPF-01.jpgLouth Crater (CTX Frame - Absolute Natural Colors; credits for the additional process. and color.: Dr Paolo C. Fienga - Lunexit Team)96 visiteThis observation shows a persistent Frost Patch located on a Mound which is inside Louth Crater. The Frost Patch has remained largely stable at least since the Viking era (such as the late 1970s). The bright Frosty Region is bounded by a Dunefield on the North/East and the so-called "Size Classes" of several of the Features forming the Dunefield probably represent generations of Dunes that were created under a variety of Dominant Wind Conditions. The Frost is largely absent over the Dunes, but it is way more stable on the Ground that does not possess Dune-shaped Landforms.

PSP_007805_2505-PCF-LXTT-IPF-00.jpgFrost all over Louth Crater (Absolute Natural Colors; credits for the additional process. and color.: Dr Paolo C. Fienga - Lunexit Team)84 visiteThis image shows the changing Seasonal Frost Patterns on Louth Crater, located at about 70° North Latitude, in the Martian Region of Vastitas Borealis. This Crater contains a Mound (---> terrapieno) covered by Water Frost that persists throughout the year (which is an unusual circumstance for this Latitude); however, even the Seasonal Carbon Dioxide (CO2) Frost deposited during the Northern Winter can reach such a Latitude. At the time this image was acquired (such as during the Northern Spring), the Carbon Dioxide Frost was in the process of sublimating back into the Martian Atmosphere. Note that there are Sand Dunes near the edge of the Mound, which become clear of Frost in the Summer.
