Global topography of Mars based on MOLA data. The Tharsis bulge is the large area at left (shown in shades of red and white). Amazonis and Chryse Planitiae are the blue areas left (west) and right (east) of Tharsis, respectively. In this image, the higher average elevation of the southern hemisphere (zonal spherical harmonic degree 1) has been removed to highlight the elevation contrast of Tharsis with the rest of the planet.

To illustrate Mauna Kea's dry prominence, imagine raising the sea level of the Pacific Ocean to submerge the top of Mauna Kea. Then slowly lower it again. The first thing to appear is the peak of Mauna Kea. Then Mauna Loa and peaks of the surrounding Hawaiian Islands will emerge from the ocean. If the ocean drains further, the island around Mauna Kea will grow and merge with the adjacent islands. Continue draining until a land bridge forms between the Hawaiian Islands and a continent so that it is possible to walk all the way there without getting wet. Stop draining at this point, and this bridge is the key col of a dry Mauna Kea, connecting it to Mount Everest. Mauna Kea's peak stands 30,610 ft (9,330 m) above this key col.
