Martian Mt. Sharp vs. Mt. McKinley

Philip Bump put together this great comparison of Earth's Mt. McKinley and Mars' Mt. Sharp (as photographed by the Curiosity rover).

Officially, it's Aeolis Mons, and it stands 18,000 feet above the crater floor. Here's how that compares to Mount McKinley, America's tallest peak at 20,320 feet. The sea levels / floor levels are roughly comparable. But this is just an approximation. Do not make wagers based on this.
