During February 2010, a salvage excavation was conducted within the precincts of the Mazor antiquities site (East; Permit No. A-5824; map ref. 196312–438/663066–139), prior to paving Road 4711, which connects Highway 444 with the city of El‘ad. The excavation, undertaken on behalf of the Israel Antiquities Authority and underwritten by the Derom Ha-Sharon Regional Council economic company, was directed by D. Masarwa, with the assistance of S. Ya‘aqov-Jam (administration), A. Hajian (surveying and drafting), H. Ben-Ari (GPS), A. Peretz (field photography) and A. Gorzalczany (guidance).
A natural cave (L100; length 1.8 m, width 3.5 m, height c. 1.3 m; Figs. 2, 3) was discovered; its northern part had been destroyed by earthmoving work prior to the excavation and therefore its original dimensions are unknown. The entrance was probably from the north. The ceiling of the cave was removed for safety reasons. The cave’s interior was filled to the top with terra rossa soil and small fieldstones, which contained a small assemblage of potsherds dating to various periods. It seems that in its last phase the cave was used for storage and subsequently served as a dwelling for shepherds.
Two stone clearance heaps were identified, one on the rock surface of the cave’s roof (L103; diam. 3. 5 m; Figs. 2, 4) and the other atop a rock surface on the northeastern side of Area A (L104; diam. 4 m; Fig. 5). Both clearance heaps consisted of medium and large stones that had been gathered from the nearby cultivation plots. Clearance Heap 104 was delimited by a wall (W110; width 0.4 m) built of large fieldstones that prevented the contents from sliding into the adjacent plots.
Three quarries were discovered, one c. 30 m east of Cave 100 (L101; Fig. 6) and two beneath Clearance Heap 104 (L108, L109; see Fig. 6). Three stones (0.3 × 0.4 m and 0.6 × 0.8 m) that had not been completely hewn and were not detached from the bedrock remained in Quarry 101. The hewn steps in Quarries 108 and 109 appear to the north, east and west. Detachment marks of the building stones are visible on top of bedrock and based on the bedrock edges that remained after the quarrying, the stones were 0.2–0.3 m in size.
A field wall (W102; width 0.6 m, length 12 m; Fig. 7) that was intended to demarcate cultivation plots was exposed on the northeastern side of the area. The wall was built of large fieldstones that were placed on brown soil without a foundation trench.
Part of a rock-hewn tomb (L200; Fig. 8) that was cut as a result of the earthmoving work prior to the excavation was exposed. It apparently had a rectangular shape (0.6 × 1.2 m, depth 1 m) and was hewn vertically from the surface. An opening covered with stone slabs was discovered at the bottom of its eastern side and bones were exposed next to it. The interior of the tomb was not excavated.
More parts of the agricultural region of the ancient tell, located to the south were revealed in the excavation, in addition to those that had been exposed in the past. The finds are indicative of agricultural activity and are similar to those discovered in previous excavations and surveys in the region.
