Top soil layer (loci 1,4,7,9) was approximately 10cm. Thick throughout the trench at which depth bedrock was exposed in major part of the trench and the trench extended east. In meters N12-15 W10 a large bedrock outcropping to the east of which the soil contained carbon and abundant archeological material and appeared as a dark lensing on the east sectino (see drawing on p. 60 ). The trench was further extended east in order to investigate the nature of the lensing. Stone formation was exposed after the top soil cut in N12-15 W9. It was about 2m in length and formed by large flattish stones layed out in an elongated lozenge shape oriented north to south. Soil around the stones was uniformely olive brown.

When the stones were lifted and surface of the trench scraped a noticeable transition in soil color became visible corresponding to an oval shape lense cut into much lighter sterile soil having approximately dimensions of 2x1.5m. Excavation proceeded with only lense being excavated in order to see the shape and extent of the feature. It turned out the be about 50cm deep from the point at which the stone formation was exposed (final depth 155cm b.d.). The soil at the bottom of the lense had appearance of sterile soil but several full profile vessel parts were recovered which appeared to have been placed directly on bedrock.
