This app helps to visualize how the Pliestocene 'Ice Age' was actually just a period of altered polar axis (ie. the north pole was over greenland instead of its present location).
This becomes obvious by investiagating the positioning of the ice cap and lack of continental glaciation in Siberia & Alaska. Note how the extent of the ice
during 'Ice Age' was actually no bigger than the current arctic or Antarctic circles. (With the exception of 'Alpine Glaciers' such as the Canadian Rockies, Alps, Russian Mountains, etc. )
Ice polygons are taken from the current scientific consensus on continental ice age icecap extents.
Toggle on the following 'Antarctic overlay layer' to see the current extent or size of Antarctica with its associated winter sea ice superimposed upon the extent of the ancient northern hemesphere ice cap. You'll see how the pleistocene ice cap was essentially what would be expected of a different polar location.
