Category:Scalloped topography
Scalloped topography is common in the mid-latitudes of Mars, between 45° and 60° north and south. It is particularly prominent in the region of Utopia Planitia,[1] [2] in the northern hemisphere, and in the region of Peneus Patera|Peneus and Amphitrites Paterae[3] [4] in the southern hemisphere. Such topography consists of shallow, rimless depressions with scalloped edges, commonly referred to as "scalloped depressions" or simply "scallops". Scalloped depressions can be isolated or clustered and sometimes seem to coalesce. A typical scalloped depression displays a gentle equator-facing slope and a steeper pole-facing scarp.[5] Scalloped depressions are believed to form from the removal of subsurface material, possibly interstitial ice, by Sublimation (chemistry)|sublimation (direct transition of a material from the solid to the gas phase with no intermediate liquid stage). This process may still be happening at present.[6] This topography may be of great importance for future colonization of Mars because it may point to deposits of pure ice.[7]
