Two lines of caves dot the eastern escarpment of Mount Sedom. They were formed at times when the lake’s surface was higher than it is today. The authors explain that the height and shape of Mount Sedom’s caves mark the Dead Sea’s rising and falling over the centuries. Based on organic remains found inside, the upper row of caves (halfway up the cliff) has been dated to the Early Bronze Age (c. 3000 B.C.E.); the caves beneath were formed in later periods when the water level was lower.
