The “PEF Rock mark” was marked by the Archaeologist Stewart Macalister in 1900, and was used as a bench mark for measuring the height of the Dead Sea for several decades.
In 1930, the height recorded by the PEF rock mark was m. -390, the heighest ever recorded.
Today (2015) the Dead Sea is m. -429 and it is receeding about 1 m. per year.
