Olympus Mons is a large shield volcano on Mars. As measured by the Mars Orbiter Laser Altimeter, it is 21.287 kilometres high, about 2.5 times the elevation of Mount Everest above sea level. It is Mar
Mars Global Surveyor image showing lava flows of different ages at the base of Olympus Mons. The flat plain is the younger flow. The older flow has lava channels with levees along the edges. Levees are quite common to lava flows on Mars.

Calderas on the summit of Olympus Mons. The youngest calderas form circular collapse craters. Older calderas appear as semicircular segments because they are transected by the younger calderas.
Oblique view of Olympus Mons, from a Viking image mosaic overlain on MOLA altimetry data, showing the volcano's asymmetry. The view is from the NNE; vertical exaggeration is 10×. The wider, gently sloping northern flank is to the right. The more narrow and steeply sloping southern flank (left) has low, rounded terraces, features interpreted as thrust faults. The volcano's basal escarpment is prominent.
Mars is the fourth planet from the Sun. It is also known as the "Red Planet", for its orange-red appearance. Mars is a desert-like rocky planet with a tenuous atmosphere that is primarily carbon dioxi
