In December 2015, five Madswimmers did the highest swim in history in lake Tres Cruces Norte in the Andes Mountains at an altitude of 5909 meters (19,386 feet) above sea level.
The Madswimmers created and then entered the lake on a volcano in the Andes Mountains along the Argentina-Chile border in South America with the water temperature between 0.5 – 2ºC (32.9ºF – 35.6ºC).
Jean Craven is shown in first video. He swam with Herman van der Westhuizen and Chris Marthinusen in a the 5-minute bioprened wild swim while Evan Feldman and Milton Brest swam in wetsuits and Robert Graaff and Juandre Human were unable to partake in the final swim due to medical restraints after a 6-hour hike up the volcano and a laborious creating of the small area to swim through the 20 cm thick ice covering.
