With the onset of summer in the Northern Hemisphere and average temperatures worldwide on the rise, the question on the minds of many is: how to beat the heat? For cavers willing to travel to Abkhazia on the eastern coast of the Black Sea, one solution might be to head underground. Krubera Cave in the Republic of Georgia, with limestone passages that extend to depths well over a mile and half, offers a particularly cool opportunity. In the last few years, teams of explorers seeking to push the record deeper have contended with hypothermia while diving through flooded parts of Krubera.
