Arctic Pole of Inaccessibility

Furthest from any landmass on the planet, the Arctic (North) Pole of Inaccessibility is not on land, but rather the northernmost mass of Arctic ice. As a result, the shifting of the ice shelf means that no permanent structures can be erected there. And they dont call it the pole of inaccessibility for nothing, theres still debate over whether or not anyone has actually ever reached it on foot by crossing the ice.
