Over 25 million years ago, as the continent of Antarctica finally split from the northern continents, the final break up of Gondwanaland, the opening of the sea that continuously circumnavigate the globe, the snow fell that would never melt. The beginning of an icy period, with ice perhaps as old as 15 million years buried underneath the massive weight of frozen water. Slowly inexorably growing into glaciers that covered a continent, spreading out and flowing to the sea. The edge as it enters the waters, eventually breaking off and calving huge massive ice. Sometimes extending beyond the land as ice shelves supported by the underlying seas. It is these glaciers, whether still connected to the ice sheet or formed on their own that create a white circumference, a battlement that surrounds this land.
