EDS Rock Art Concession:

The Eastern Desert Survey was formed in 1997 by David Rohl to re-record much of the predynastic rock-art first discovered and noted by Arthur Weigall in 1907 and then again by Hans Winkler in the 1936. The expeditions involved found many new sites and these have now been photographed and logged. There are still many wadis in the area that have not been explored to date.
