Within three days, Shackleton chooses a small crew and leaves, in the largest of the boats, the 22 footer, to attempt a daring and dangerous crossing. They must attempt to get to a whaling station in Stromness Bay on South Georgia Island. He leaves his men on Elephant Island and sets out. He takes the navigator with him, as they must hit a point of land merely 25 miles across, in a vast sea. It is an ungodly attempt in such a small boat, to cross the waters they cross, with howling hurricane force gales, rip currents and monster waves. But they make it. They make landfall, find water.
They have landed in King Haakan Bay on the west side of South Georgia Island. Shackleton sets off across high mountains, glaciers, in ragged clothing, with just one claw hammer and 50 feet of rope and two crew members. He must achieve the whaling station he left 522 days earlier, in Stromness Bay, on the eastern short of the island. They have to cross the glaciers to find the whaling village.
