6,395 m (20,981 ft) — Marcel Korkuś (Poland) dived through the frozen surface of a natural water reservoir—too small to be considered a lake—near the summit of Ojos del Salado, the highest volcano in the world, on December 13, 2019. The record dive took place during his third expeditionary attempt to reach the site (2016, 2018, 2019). Ice thickness was 1.3 m (4.3 ft) and water temperature was 3°C (37.4°F). Korkuś was supported by a three-person surface crew composed of Uli Kusnezov, Eduardo Salas, and Martin Alderete.
