Stratum V. This stratum is characterized by a reddish brown layer of grumusol, devoid of any remains.
Stratum IV. An accumulation of gray soil, rich in small angular stones. This stratum contained a large quantity of flint items, mainly the debitage of naviform blade production. Sickle blades, arrowheads, drills, scrapers and a variety of other tools were also discovered. The stratum dates to the middle of the Pre-Pottery Neolithic B.
Stratum III. A wide pit that was dug into Stratum IV. The pit was filled with soil containing numerous flint items and pottery ascribed to the Nahal Zippori horizon, which dates to the end of the Pottery Neolithic period (Getzov, Milevski and Khalaily in press). A fragment of a large stone basin was found at the bottom of the pit. 
Stratum II. This stratum consisted of an accumulation of brown-gray soil and numerous fieldstones. Many flint items, and pottery sherds, dating to the Early Bronze Age IA were found between the stones. Several sherds that are ascribed to the Nahal Zippori horizon and the Late Chalcolithic period (Ghassulian culture) were also discovered in this stratum. This is the first time that pottery of the Late Chalcolithic period was found at the site of Yiftah’el, but there is not enough to identify cultural affiliation.
Stratum I. An accumulation of light red-brown soil, containing a small number of flint tools, pottery from the Intermediate Bronze Age, and many small pottery sherds from the Middle Roman period.
Past excavations yielded valuable information about the earliest settlements at the site, but the boundaries of the settlements and the population size in the different periods are still insufficiently known. The current excavation contributed to our knowledge regarding the extent of the settlement in the different periods, and uncovered previously unknown remains from the Late Chalcolithic site.
