Four main geological units (1–4) were discerned within the excavation area.
Unit 1 comprised basal vesicular basalt, possibly the remnant of an ancient flow.
Unit 2, limited to the southwestern section of the excavation, was the Kinneret formation, composed of crossbedded layers of marl, coarse sand, and limestone and basalt pebbles and boulders. These layers represented several depositional environments that reflected the dynamic changes of the Kinneret palaeolake over the course of thousands of years.
Unit 3 (Fig. 5) was a thin coating of travertine that appeared in limited areas of the northeastern quarter of the excavation. The travertine coated and abutted portions of the Unit 1 boulders. Embedded in the upper surface of the travertine were flint artifacts, bones, freshwater shells (mainly Melanopsis), a freshwater crab claw and possibly root and bark imprints. The localized travertine crust indicated the existence of a prehistoric fresh-water spring, which appears to have attracted human occupation.
Unit 4 was the main anthropogenic and depositional archaeological accumulation. It comprised paleosols that contained chalk concretions, angular small limestone and worn basalt cobbles.
The oval structure (diam. 4.75 m; Fig. 6) was built of unworked fieldstones. Construction of the channel destroyed the eastern portion of the structure .Its wall was preserved to a maximum of four courses high (c. 0.7 m; Fig. 7). No entrance was discerned. Several living surfaces (combined depth c. 0.45 m) that consisted of compacted brownish gray fine palaeosol were identified. In comparison to the artifact density outside the structure, the density within was rather low. The finds consisted of flint artifacts, Dentalium, bones and sporadic patches of charcoal. The flint artifacts included small lunates modified by Helwan retouch (Fig. 8) and sickle blades dating to the Natufian period; the bones represent gazelles, small mammals, turtles, birds and a few fish.
An open area, adjacent to the north of the structure, contained the majority of ground-stone artifact fragments (pestles, mill stones and pounders). A human burial was uncovered on a stone surface, 1.5 m to the northwest of the structure (Fig. 9). Only the upper half of the skeleton was preserved. The skull was likewise missing but the lower jaw was found in situ, facing north. The interred was lying unusually on his chest (Figs. 10, 11) and a single fluted Dentalium was found on his torso.
South of the structure, only evidence of the Kinneret formation and its sedimentation were identified and no human-related artifacts were retrieved.
In addition to the clear Natufian presence, flint artifacts, e.g., el-Khiam points and awls on bladelets with miniature points, dating to the PPNA (11,000–9,500 cal. BP) were retrieved from the palaeosol (Fig. 12). Their presence suggests a possible PPNA occupation in close proximity to the Natufian finds.
The eastern excavation area was a narrow strip between the water channel and the descending slope (length c. 25 m), two meters lower in absolute height than the western area. The stratigraphy of this area differed somewhat from that of the western one. Three layers were discerned and the most significant one was the lowest, which consisted of a light brownish gray paleosol rich in Natufian archaeological material with a few later intrusions. No architectural remains or a clearly defined living surface were revealed in this area and it is not as yet clear whether the Natufian finds were in primary deposition.
