Overview:The teams take off from their Pit Stop, an active volcano at Mirador Cotopaxi. They receive a clue instructing them to travel 7,400 miles to Santiago, Chile and then take a taxi for 17 miles to the headquarters of Codelco. There, the teams take part in a Roadblock that is ultimately rendered largely meaningless when they all make the same flight traveling 230 miles to Chuquicamatta in Calama, Chile. Once at their destination, the teams put on their safety gear and take part in a Detour that requires them to choose between two tasks traditionally involved in Chilean mining operations. The teams then use marked vehicles to travel the treacherous Valley of the Moon before emerging on safer ground and heading for the Pit Stop at the Valley of the Dead. One team makes a crucial mistake by failing to properly read a clue and posted signs regarding a speed limit. Due largely to this mistake, they fall behind and are eliminated from the race.
