The Rupes Nigra ("Black Rock”) believed by many to be a the highest mountain on earth.

Black rock located at the Magnetic North Pole, “33” French miles in size, it provided an explanation for why all compasses point to this location. The island featured on maps from the sixteenth and seventeenth centuries, including those of Mercator and his successors.

In the midst of the four countries is a Whirl-pool, into which there empty these four indrawing Seas which divide the North. And the water rushes round and descends into the Earth just as if one were pouring it through a filter funnel. It is four degrees wide on every side of the Pole, that is to say eight degrees altogether. Except that right under the Pole there lies a bare Rock in the midst of the Sea. Its circumference is almost 33 French miles, and it is group.

The largest shareholder in the world “BlackRock” is named after this mountain 🏔️.
