Ernest Shackleton

We just learned about the explorer Robert Falcon Scott.

Another famous Antarctic explorer is Ernest Shackleton.

Shackleton had been on an expedition before with Robert Falcon Scott, but got sick and was sent home.

In 1908 he took a ship called the Nimrod to Antarctica, and were the first team to climb to the top of Mount Erebus, the tallest mountain in Antarctica.

In 1914 Roald Amundsen had already made it to the South Pole, so Shackleton went back to Antarctica to try and be the first person to cross all the way from one side of Antarctica to the other.

Shackleton took 2 ships, the Endurance and the Aurora.
The Endurance would land at the north side by the Weddell sea where they would start their journey, and the Aurora would land at the other side by the Ross sea as the ending point of their journey.

In 1915 the Endurance landed, but got stuck in the ice and sank into the sea.
The crew was stranded there with no way to get home and not enough supplies to get across Antarctica.
Shackleton led some of his men north across some of the ice, and on lifeboats to get hundreds of miles away to an island where they could be rescued.

In 1921 Shackleton was going to lead another expedition to try and sail all the way around Antarctica, but got sick and died before he could go on the journey.
