Miles BASE jumped from the top of the Treasury in the depth of the Lost City of Petra and landed directly in front of it, in less than 15 seconds, going 20 miles per hour, in a canyon that is 100 feet wide. The challenge was in the short length and altitude of the jump and the incredibly small and tight space that left Miles with little room to be able to escape the walls of the limestone mountains, which he did with flying colors, to become the first BASE jumper to attempt such a leap!
