017- Dead Sea
Bitumen is a heavy, black byproduct of crude oil distillation, used today mostly for paving roads (asphalt). Bitumen occurs naturally in the Dead Sea where it is released from the bottom of the lake by earthquakes. The Dead Sea bitumen was used in prehistoric times to attach arrow heads to wooden shafts; the Ain Ghazal inhabitants used it to decorate their statues; the Babylonians used it to waterproof boats; the Sumerians used it as a cement; the Egyptians used it in cosmetics, medicine, and mummy embalmment; the Romans used it as a waterproof sealer; and the Nabateans extracted and traded it.
South of the Dead Sea. Found floating on the surface or washed onto the shore in large or small blocks, mainly after earthquake activities.
