Peter J. Mouginis-Mark 2021 vector digital data The volcano Olympus Mons is probably the best known extraterrestrial volcano. The summit comprises a nested caldera with six overlapping collapse pits which collectively measure ~65 x ~80 km in diameter. Numerous wrinkle ridges and graben occur on the caldera floor, and topographic data indicate that there has been greater than 1.2 km of elevation change since the formation of the floor as a series of lava lakes. The paths of lava flows on the south and southeast flanks do not conform to present day topography. Mapping at a scale of 1:200,000 shows that the summit area displays a complex volcanic history, with numerous similarities with terrestrial shield volcanoes. Pangboche crater is a large (~10 km diameter) crater of impact origin that lies on the south flank of the caldera and, because of the elevation and lack of volatiles, displays numerous features more similar to fresh lunar craters than impact craters on Mars.
