The survey revealed the presence of natural rock shelters and caves in the slopes of the lower end of the system, some of which were reported by Cohen's team in the earlier survey. Some of these rock shelters and caves appear to have been used as matmarot or storerooms by the Beduins, who also used them for burials, probably in modern times. Soundings (1 × 2 m) were excavated behind terraces at the lower extreme of the system, next to the excavated farmhouse, and in the upper extreme of the system. Random core samples were extracted throughout the wadi and soil samples were analyzed in the laboratories of Cambridge University.
