Area A. Nine excavation squares (C17, C18, C20, D3, D7, D11–D14) were opened and two work surfaces were exposed on a north–south axis, c. 10 m apart. The northern surface was revealed in Sqs D11–D14 (L110, L113, L114, L116, L117, L120, L124, L126, L132, L133; Fig. 3) and the southern surface in Sqs C17 and C18 (L112, L118, L125; Fig. 4). Both surfaces were built of dense conglomerate, consisting of small and medium fieldstones, river pebbles and pottery sherds, above a light-brown bedding of numerous small pottery sherds, river pebbles, crushed chalk and animal bones. Remains of a burnt layer (L122) were exposed below the northern part of the northern work surface in Sq D11. In Sq D12 a layer of pottery sherds (L115) and a concentration of burnt clay bricks and charred material (L111), probably the remains of an installation, were revealed on the work surface. The excavation of the northern surface exposed fragments of pottery, mainly of the Roman period. The pottery included a fragment of Kefar Hananya casserole dating to the first–third centuries CE (Fig. 5:3), and fragments of vessels from the third–fourth centuries CE, among them bowls (Fig. 5:1), casseroles (Fig. 5:2), cooking pot (Fig 5:4), Galilean jars (Fig. 5:5) and bag-shaped jars (Fig. 5:6, 7). An intact Late Roman juglet (Fig. 6) was exposed on the southern work surface in the section of Sq C18. Fragments of pottery, mainly dating to the late Byzantine period (sixth–seventh centuries CE), were discovered in the excavation of the southern surface, including a fragment of a bowl imported from Asia Minor (PRSW/LRC 3; Fig. 5:8), a bowl with kerbschnitt decoration (Fig. 5:9), Galilean jars (Fig. 5:10), rim fragment of a Galilean jar dating to the end of the Byzantine – Umayyad periods (seventh–eighth centuries CE; Fig. 5:11), jugs (Fig. 5:12) and a stopper for a bag-shaped jar, dating to the sixth–seventh centuries CE (Fig. 5:13). The pottery which was recovered from both work surfaces was mixed and abraded for the most part, and seems to have been part of a fill that was brought from the surrounding area to construct the surfaces. Due to the proximity of Nahal ‘Ada, the pottery was disturbed and mixed repeatedly by surface-wash and flooding. Bedrock devoid of ancient remains (Fig. 7) was discovered in the northernmost square in the area (Sq D3). There were no antiquities in Sq D7 due to past flooding. Alluvium (L134) was revealed in the southernmost square (Sq C20).
Area B. Five excavation squares (4 × 4 m; C3, C4, C6, C7, D11; Fig. 8) were opened in this area, and each was subdivided into four (2 × 2 m). The scope of the excavation was reduced and focused on Sqs C6 and C7 after the area had flooded, and sections in the squares collapsed. Alluvial layers containing limestone, river pebbles and a large quantity of flint items were exposed. The flint items were all abraded and covered with yellowish brown patina. Most of them were natural chunks, but several tools and some debitage were also found, mostly non-diagnostic. The only indicative tool is a retouched Levallois flake (L206; Fig. 9:1). A Levallois core (L205; Fig. 9:2) was among the debitage discovered. The Levallois items date part of the assemblage to the Middle Paleolithic period (Mousterian culture). Judging by the physical condition of the flint items it seems that they were washed from a nearby site.
The two work surfaces in Area A indicate industrial activity. A segment of road which was discovered nearby may have led to this area and connected the site to settlements along the road in the Roman and Byzantine periods. The flint items in Area B show that a Middle Paleolithic site was located nearby, next to Nahal ‘Ada.
