The Ohalo II fisher-hunter-gatherers' submerged camp was found in 1989 after a long drought, on the shore of the Sea of Galilee. Dated by 14C to an average 19,500 B.P. (calibrated ca. 23,000 B.P.). Due to excellent preservation conditions under the water, the remains of daily activities in the camp have been discovered in situ. These include the remains of the oldest brush huts ever found in the world, concentrations of open-air hearths, a human grave and other installations. Hundreds of thousands of charred seeds/fruits, animal bones and flints were discovered on the brush huts' floors and around open-air hearths. The excavations were directed by Prof. Dani Nadel.
