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 (Tasmania) Mount Olympus (Tasmania) Mount Olympus is a mountain in the Cradle Mountain-Lake St Clair National Park in Tasmania, Australia. It is the 24th highest mountain in Tasmania at above sea level and is situated about South-East of Mount Gould and about west of Lake St. Clair. In 1835 George Frankland climbed the mountain and named it Mount Olympus. Mount Olympus was painted by the Australian landscape painter, William Charles Piguenit. It was purchased by the Art Gallery of New South Wales in 1875 and was the Gallery's first oil painting acquisition, "the first Australian work purchased by public subscription", and
