HiRISE image of channelized lava flow with levees on Northern flank of Ascraeus Mons. Much of the heat stored inside the planet when it formed has been lost, and the outer crust of Mars is too thick to allow molten rock from deep below to reach the surface. [7] The southwest-northeast orientation of the aprons matches the orientation of the Tharsis Montes, suggesting that a major fissure or rift in the Martian crust is responsible for the orientation of both the aprons and the Tharsis Montes chain. The Tharsis region is thousands of kilometers across and averages nearly 10 km (33,000 ft) above the mean elevation of the planet. Similar deposits are also found at the northwestern edges of the other two Tharsis Montes, Pavonis Mons and Arsia Mons, as well as on Olympus Mons. Whether the channels were formed predominately by water or lava is still a topic of debate,[28] though extensive study of analogous environments (e.g. d. Arsia Mons.

A group of three smaller volcanoes (the Ceraunius-Uranius group) lies about 700 km to the northeast, and Pavonis Mons (the middle volcano of the Tharsis Montes) lies 500 km to the southwest. The volcano was originally called North Spot[2] because it was the northernmost of only four spots visible on the surface due to a global dust storm that was then enshrouding the planet. 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. In terms of volume, Olympus Mons is 100 times greater than even the largest volcanoes present on our planet. Volcanoes are formed when the hot molten lava, ash, and gases trapped inside the Earth’s surface find an outlet, through a fissure or opening in a planet’s crust. Today's VIS image is located on the summit of Ascraeus Mons, one of the three large Tharsis region volcanoes.
