During April 2009, a survey was conducted in the region of Beqo‘a (License No. S-83/2009; map ref. 191–6/633–7), prior to the installation of a sewer line. The survey, on behalf of the Israel Antiquities Authority, was performed by P. Betzer and D. Ein-Mor, with the assistance of D. Levy (GPS) and H. Khalaily (flint artifacts).
The survey area extended from Qibbuz Nahshon to Moshav Tal Shahar (length c. 6 km), in a valley with tributaries of Nahal Nahshon and Nahal Gezer. A single extensive site (c. 4,000 sq m) with numerous flint cores and flakes, which could not be dated, was documented. A multitude of flint tools had previously been discerned in at least two of the many sites (Nahshon South and Khirbat el-‘Asfura) that occur on the hills on either side of the valley. The flint cores and flakes at the site in the valley were probably swept over from the sites on the adjacent hills; were not necessarily anthropogenic debris, but could have been created naturally.
