The Great Ice Barrier is the edge of the ice shelf
that extends for hundreds of miles. It is where the glaciers that
flow from the Antarctic land mass, leave and begin to float on the sea
providing a cliff of ice with only very rare places where a landing
is possible. These ice-cliffs prevented many of the early explorers
of Antarctica from making landfall causing them to sail for days until
a place could be found where a small boats crew could get ashore.
