Glaciers formed much of the observable surface in large areas of Mars. Most of the area in high latitudes, especially the Ismenius Lacus quadrangle , is believed to still contain enormous amounts of water ice. [1] [2] Recent evidence has led many planetary scientists to believe that water ice still exists in the form of glaciers that are covered with a thin layer of insulating rock. [3] [4] [5] [6] [7] [8] In March 2010, scientists released the results of a radar study of an area called Deuteronilus Mensae that found widespread evidence of ice lying beneath a few meters of rock debris. [9] [10] Glaciers are believed to be associated with Fretted terrain , [11] many volcanoes, [12] [13] and even some craters. [14] |
