Atlas the Titan, the Atlas vertebrae, and Atlantis as the continent that carries the sky or the Earth

About "Atlantis", Atlas the Titan carried the Earth or the sky or whatever, the Atlas vertebrae carries the head, perhaps Atlantis was positioned at the pole.

The ice sheet during the last "ice age" was oriented with Greenland as the center of it, Greenland was the former north pole.

Roughly opposite to Greenland you also find the Wilkes Land anomaly, that could be the former polar hole filled with basaltic lava. This "crater" is 500 km across, a "mascon" meaning the density is higher than the surrounding region, and continental rock has lower density than basaltic rock.

If you look at maps that show Atlantis, it looks a lot like Greenland.
