- A glacier of considerable thickness and more than 50,000 km2 in
area, forming a continuous cover of ice and snow over a land surface,
spreading outward in all directions and not confined by the underlying
topography; a continental glacier. Ice sheets are now confined to polar
regions (as on Greenland and Antarctica), but during the Pleistocene Epoch
they covered large parts of North America and northern Europe. AGI
