The 621 mile-by-1,240 mile (1,000 by 2,000-kilometer) region of Tyrrhena Terra (outlined by the white box in the inset) sits between two regions of low altitude in Mars ' southern hemisphere, as shown in this global topography map. Hydrated minerals were found in 175 locations associated with impact craters in Tyrrhena Terra.
