Olympus Mons in 3D

Mars · the summit caldera rim

Tharsis region, Mars

Olympus Mons is the tallest volcano known in the solar system, about two and a half times the height of Everest above sea level. This 3D walk puts you on the rim of its summit caldera, a nest of collapse pits left when magma chambers drained, with the far wall dropping almost three kilometres to the floor. Its slopes are so gentle that the base, some 300 km away, is out of sight.

Where: Tharsis region, Mars
Height: About 21.9 km above the Martian datum
Summit caldera: About 80 km across; walls up to 2.8 km
Footprints: None: every landing so far was in the lowlands

The caldera wall
Known
The ground drops about 2.8 km from this rim to the caldera floor. The whole summit caldera is some 80 km across, a nest of collapse pits left when magma chambers drained.
21.9 km above the datum
Known
Olympus Mons is the tallest volcano known in the solar system, about two and a half times the height of Everest above sea level. Its slopes are so gentle that from here you could not see its base: it is 300 km away.
Nobody has stood here
Known
This is a reconstruction from NASA orbital elevation data. Mars has no footprints above its deserts yet: every surface mission so far landed in the lowlands.
