The elevation of the plains averages about 3 km above datum (Martian "sea" level), giving the volcano an average vertical relief of 15 km. The origin of these deposits has been debated for decades. Like most of the Tharsis region, Ascraeus Mons has a high albedo (reflectivity) and low thermal inertia, indicating that the volcano and surrounding areas are covered with large amounts of fine dust. First Descent into Devil's Throat. Patterned ground polygons on Mars (left) and in Antarctica (right) Layering of sediment and permanent ice at Marsâ south pole .

It is also 370 miles, 600 kilometers, in diameter and has slopes much like Earth's Hawaiian volcanoes. The visible lava tubes are caused by the crusting (or cooled lava) which occurs over a lava channel, a covering making the channel into a tunnel. Individual terraces are not continuous around the volcano, but instead consist of arcuate segments that overlap with each other, forming an imbricate pattern. However, recent geologic evidence suggests that FSDs are deposits left by glaciers, which covered portions of the volcanoes during a recent period of high obliquity. These rates are comparable to those seen in Hawaii and Iceland. It was discovered by the Mariner 9 spacecraft in 1971. The atmospheric density is too low to mobilize and remove dust once it is deposited. Closeup of pit northwest of Ascraeus Mons.
