The dry prominence of Mount Everest is, by convention, equal to its wet prominence (8848 m) plus the depth of the deepest hydrologic feature (the Challenger Deep at 10,911 m), or 19,759 m. The dry prominence of Mauna Kea is equal to its wet prominence (4205 m) plus the depth of its highest submerged col (about 5125 m), or about 9330 m, giving it the world's second greatest dry prominence after Mount Everest. The dry prominence of Aconcagua is equal to its wet prominence (6962 m) plus the depth of the highest submerged col of the Bering Strait (about 50 m), or about 7012 m.
