Deep sea diving teams will be dispatched to attempt to decode the meaning of the monolith, Live Science reports:
A giant “monumental” stone structure discovered beneath the waters of the Sea of Galilee in Israel has archaeologists puzzled as to its purpose and even how long ago it was built. Rising nearly 32 feet high, the mysterious structure is cone shaped and weighs an estimated 60,000 tons. That makes it heavier than most modern-day warships.
It appears to be a giant cairn, boulders piled on top of each other. Structures like this are known elsewhere in the world and are sometimes used to mark burials.
The structure was first detected in 2003 during a sonar survey of the southwest portion of the sea. Divers have since been down to investigate, they write in the latest issue of the International Journal of Nautical Archaeology. The researchers say the structure is definitely human-made and probably was built on land, only later to be covered by the Sea of Galilee.
