Here's 3 different maps depicting similar North Pole aka Arctic. As some are focused on Antarctica, I believe that it is also very important to learn what is hidden on Arctic too.

Maps:

A. Urbano Monte map from 16th century
B. 1606 Mercator Hondius Map of the Arctic
C. Map that VK shared

What lies in the center on some maps is called Hyperborea (pic #2 ).

The map matches Olaf Jansen's description. There's a transcript of Olaf Jansen's account of his journey to Inner Earth titled: The Smoky God.

The city of "Eden" is located in what seems to be a beautiful valley, yet, in fact, it is on the loftiest mountain plateau of the Inner Continent, several thousand feet higher than any portion of the surrounding country. It is the most beautiful place I have ever beheld in all my travels. In this elevated garden all manner of fruits, vines, shrubs, trees, and flowers grow in riotous profusion.

In this garden four rivers have their source in a mighty artesian fountain. They divide and flow in four directions. This place is called by inhabitants the "navel of the earth," or the beginning, "the cradle of the human race." The names of the rivers are the Euphrates, the Pison, the Gihon, and the Hiddekel.

I think this may be the real Eden.
