A recently discovered artificial stone mound on the northern shore of the Dead Sea is a maritime feature exposed by the drying of the lake. Lake-level fluctuations, a loose silt bottom, lack of natural anchorages, and onshore prevailing winds, prevented the long-term planning, construction and maintenance of shore-based harbour installations in this area. This and a similar mound nearby, Rujum el Bahr, are interpreted as structures once used for open-water mooring, providing a firm anchor-hold over a range of lake levels and wind directions. As such, they enabled the use of this economically and strategically important part of the lake by maritime traffic.
