Olympus Mons Mons aureole deposits (discussed below). Olympus Mons lies at the edge of the Tharsis bulge, an ancient vast volcanic plateau likely formed by the end of the Noachian Period. During the Hesperian, when Olympus Mons began to form, the volcano was located on a shallow slope that descended from the high in Tharsis into the northern lowland basins. Over time, these basins received large volumes of sediment eroded from Tharsis and the southern highlands. The sediments likely contained abundant Noachian-aged phyllosilicates (clays) formed during an early period on Mars when surface water was abundant, and were thickest in the northwest
Olympus Mountain Running Olympus Mountain Running Since 1986, nearly every year, various initiators organize marathons in the Olympus Mountains in Greece. For these Olympus Marathons the classic distance of 42.195 kilometers provides a clue to the distance of some of the runs in the Olympus. Starting in 2010, events established that surpass the classic marathon distance. In some races, runners run over distances of 57 km, 70 km or almost 100 km. At the stations along the route, the runners are provided with drinks and snacks and mostly medical aid. They are offered water, electrolytic drinks, bananas, salty biscuits, sandwiches, chocolates and more.
