Gravity of Mars noted that older regions on Mars are isostatically compensated when the younger region are usually only partially compensated. Different volcanic constructs could behave differently in terms of gravity anomalies. Large volcanoes Olympus Mons and the Tharsis Montes produce the largest positive free-air gravity anomalies in the solar system. Alba Patera, also a volcanic rise, north of the Tharsis Montes, however, produces negative Bouguer anomaly, though its extension is similar to that of Olympus Mons. And for the Elysium Mons, its center is found to have slight increase in Bouguer anomalies in an overall broad negative anomaly context in the Elysium
Mount Olympus of the coin. Above the scene is written, in Greek, "National Park Olympus". Mount Olympus Mount Olympus (; "Olympos", for Modern Greek also transliterated "Olimbos", or ) is the highest mountain in Greece. It is located in the Olympus Range on the border between Thessaly and Macedonia, between the regional units of Pieria and Larissa, about southwest from Thessaloniki. Mount Olympus has 52 peaks, deep gorges, and exceptional biodiversity. The highest peak, Mytikas (Μύτικας "Mýtikas"), meaning "nose", rises to . It is one of the highest peaks in Europe in terms of topographic prominence. Olympus is notable in Greek mythology
