All in snow and in wooded areas which will dampen the fall
The falls were still something like 18,000 feet. how deep does the grand canyon go? is there trees on the side?

The human body is capable of amazing feats.
EDIT: "Alan Magee, a gunner on a B-17 with the 303rd Bomb Group of the U.S. 8th Air Force, was on a mission to St. Nazaire, France in January of 1943, when his bomber was set aflame by enemy fire. He was thrown from the plane before he had a chance to put on his parachute. He fell 20,000 feet and crashed onto* the skylight of the St. Nazaire train station. His arm was badly injured, but he recovered from that and other injuries."
