[1] Moderately sized, but of significance for the study of the Pre-Pottery Neolithic A period in Lebanon, it was excavated in 1972 and 1974 by Bruce Schroeder as part of the University of Toronto's investigation of Paleo-human occupation throughout the Beqaa Valley in the west.

[2] Resumed investigation into the prehistoric land use of this site were carried out in 2001, directed by Alex Wasse of the Council for British Research in the Levant.

Heavy snowfall lasts into spring, which provides water for areal irrigation into June, of some of the historically richest Levantine pastures.

[5] Research suggests, that there are strong elements of continuity between the Natufian (as the last Levantine Epipaleolithic culture) and the PPNA as evidenced by tool comparison.

Analysis of chipped stone tools revealed similarities to the Jericho Sultanian style, suggesting more advanced activities than carried out at other PPNA sites.
