Earth’s greatest vertical drop
If you jumped off Mount Thor in Canada, you would fall for nearly a mile before you hit the ground. At 1,250 m (4,101 ft) it is the steepest and tallest cliff in the world.
More than 30 attempts were made to scale the mountain until eventually in 1985 a four man American team succeeeded. It took them 33 days. The first free climb of the Southwest Buttress was made in 2012 by Bill Borger and John Furneaux. Half way up their backpack broke and their equipment fell 2000 feet below meaning they had no gear left if they wanted to climb back down. Having no means of retreat they had no choice but finish the climb or die trying.
