Geologic maps of science study area 3, Olympus Rupes, Mars

Olympus Mons is the largest known volcanic construct in the Solar System; it is more than 600 km across and more than 27 km above datum. The volcano and the great scarp that bounds it have been the subject of much scientific controversy. Although it has been possible to generate an empirical model that closely resembles Olympus Mons, the dynamics of scarp formation are still unproven. The scarp area is thus a logical selection as a scientific study area. It has also been designated as a a candidate site for a proposed lander/rover/sample-return mission to Mars not only because the site may provide information about the origin of the scarp and the evolution of Olympus Mons, but also because rocks of widely diverse ages may be studied from samples collected from talus at the base of the scarp.
