7/20/06 Under cloudy skies we continued to descend in loci E631 and E659 today, both abutting our EB terracing wall. A large portion of the day was spent cleaning off the sandy E659 matrix from emerging bedrock at the southern trench wall. As the day proceeded we cleaned northward and pulled stones as necessary. The highest bedrock point was the SE corner of the locus and the bedrock ran down slope from there. The bedrock also descended at the northern edge of the locus against the E662 EB wall, which we first considered to represent some kind of builders' trench. Which the discovery of an apparent stone "door"? or "gate"? propped against the E662 wall (on it southern face) as well as a lentil stone and vertical packing rocks, it appears that this cut within E659 (now called E663) is in fact dug to prepare an EB tomb entrance. High amounts of human skeletal material were present in both loci E659 and E663 - some of them appearing to be quite young, including an unfused illium / ischium-pubis set. In locus E631 we cleaned the majority of the locus down to bedrock and cleared a wall fall where it was present. This bedrock slopes downhill as well. In the most western portion of locus E659 I am still dubious about the architectural character of several of the linear stone arrangements. Tomorrow I will be extensively cleaning here in order to determine the relationship between these stones and walls E661 and E662.
