📖 History of Kleifarvatn
The lake sits in a volcanic caldera on the Reykjanes Ridge and has no visible outlet — water drains away through fissures in the volcanic rock below. Following a major earthquake in 2000, cracks opened in the lake bed and the water level dropped dramatically over several years, shrinking the lake significantly. The surrounding lava fields are hauntingly beautiful, and the lake has a reputation for being one of Iceland's most photogenic and otherworldly landscapes.
