Agricultural Terraces. Ten agricultural terraces (5–7, 19, 22, 24, 26, 28–30; Figs. 1–3) along the wadi and spanning it were recorded. The terrace retaining walls were built on top of high natural bedrock on the southern slopes of the wadi (max. length c. 10 m). The longer walls were built mainly on the lower part of the slope.
Rock-hewn Basins. Three rock-hewn basins (1, 3, 4; diameter 0.37–0.48 m, depth 0.16–0.24 m; Figs. 4, 5) were exposed. Their edges (width 0.08–0.10 m) were dressed to accommodate a cover, and each had a small, shallow central sump. These may have been used to produce small amounts of oil.
Natural Caves. Three natural caves (2, 25, 27) were documented.
Quarrying Debris. A heap of quarrying debris (20; 2.0 × 3.5 m) was found near a large quarry (below, 16).
Quarry. A large quarry (16; c. 30 × 50 m; Fig. 6) was exposed in the middle of the wadi; its southern part, located near an area slated for development, was partially excavated. Different-sized stones were quarried. The rock-cuttings in the west of the quarry showed detachment marks indicating that the stones quarried and detached there were smaller than the stones removed from the eastern part of the quarry. The quarry’s height varied. In the east, where numerous stones were removed, the sides were high, whereas in the west, where fewer stones were hewn, the sides were shallow (Fig. 7). The quarrying and severance marks reveal how the stones were detached from the bedrock. First, deep diagonal grooves were cut to mark the blocks designated to be detached; then, the fill was removed from the grooves, enabling the insertion of an iron bar to sever the stone (Fig. 8). Some stones were partly detached, and several completely dressed blocks were left in place (Fig. 9).
The main features documented and excavated during the excavation were agricultural installations—basins and agricultural terraces—of indeterminate date. The region was used in antiquity for farming and presumably, olives and vineyards were cultivated. Based on the area’s proximity to Umm al-‘Umdan, it is probable that the area was used by villagers from that site. The quarry unearthed during the excavation is the largest ever excavated in Modi‘in. It produced many stones, enough, perhaps, for a medium-sized settlement. Although there are no datable finds, the proximity to Umm al-‘Umdan suggests that the stones were used in the construction of the settlement and its synagogue.
