Ice-cap synonyms

Over the deepest valleys of the land in the interior this ice-cap must be at least 6000 or 7000 ft.

Modern naturalists consider that many of the problems of Australia's remarkable fauna and flora can be best explained by the following hypothesis: - The region now covered by the antarctic ice-cap was in early Tertiary times favoured by a mild climate; here lay an antarctic continent or archipelago.

Only occasionally there emerge lofty rocks, isolated but not completely covered by the ice-cap; such rocks are known as nunataks (an Eskimo word).
