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 (Utah) Mount Olympus (Utah) Mount Olympus in the U.S. state of Utah is one of the most prominent and recognizable mountains viewable from practically every location in the Salt Lake Valley. Mount Olympus is not the tallest peak along the Wasatch Front, but its unusual form and location make it a popular hiking destination for locals. The mountain is situated immediately east of the center of the Salt Lake Valley (due east from Murray and Taylorsville). Distinctive features of the mountain are its twin peaks and other outcroppings, the highest of which is called "Summit Peak" and which towers above the
