A rock climber at the Grand Canyon fell about 90 feet on Sunday . . . landed at the bottom of a "slot canyon," which is like a cave . . . and somehow didn't even get hurt.
He posted this GoPro footage and it looks like he bounced off the walls a few times, which probably slowed him down. Then he starts moaning after he lands. But a few seconds later, he yells up to his friend that he's okay.
He went to the emergency room after he hiked back to his car, and they did a full-body CAT-scan. But he was fine, and they couldn't even find a scratch on him.
