In January 2014, a trial excavation was conducted along the western edge of Horbat Kosher (Permit No. A-6980; map ref. 213260–416/743640–943), prior to paving a road. The excavation, undertaken on behalf of the Israel Antiquities Authority and financed by the Cross-Israel Highway Company, was directed by A. Nagorsky (field photography), with the assistance of E. Bachar and Y. Amrani (administration), M. Kahan and R. Mishayev (surveying and drafting) and E. Belashov (plans).
Stone Clearance Heaps. The heaps were scattered across the surface of the excavation area; some stood alone, and some clustered (e.g. L16; Figs. 2, 3). They were composed of small fieldstones placed on the surface of rock outcrops. The soil around the rock surfaces contained scant amount of worn pottery sherds dating to the Byzantine period.
Field Walls. The walls divide the area into cultivation plots. One wall (length 47 m, width 1 m) bordered the eastern part of the excavation area. It was built of two rows of medium sized fieldstones that were placed on their long side. The space between the two rows was filled with small fieldstones mixed with clay, which contained several pottery sherds dating to the Byzantine period. The wall was set directly on the bedrock, with no foundations, and was preserved to a height of one course. Another wall (length 34 m, width 1 m; Fig. 4) was built of two adjacent rows of large fieldstones and was preserved to a height of one course. A third wall (W25; length 38, width 0.85 m; Fig. 5) was built of medium and large fieldstones arranged randomly in rows. It was partly founded on the bedrock and partly on a fill consisting of soil and small stones, with several small sherds dating to the Byzantine period.
