Thursday, July 13 2017 AM We began the day with continuing to remove the N stone wall of the rectilinear structure overlying the floor of EPOC4. Stones are medium or large sized, some with maximum dimensions approaching 50cm. We used hand picks and trowels to loosen and remove the stones and used a pickaxe to remove the second and last-remaining stump from the wall. The stones of the wall are held in place by a claylike, olive brown soil with white inclusions. Soil was hand sorted in the trench then screened through a 1cm gauge sieve. We found moderate quantities of pottery and bone but few fragments of tile. When we removed one of the large stones from the eastern end of the wall and screened the loose soil from around and under this rock, we found a sherd of stamped pottery (Find #11). The stamp may be part of a quadruped or a lotus palmette. As we finished removing the last of the N wall, we opened Locus 3, which encompasses the western wall of the rectilinear building overlying EPOC4’s floor. We will remove the W wall like we’ve removed the N wall. As the light was even, opening photos of Locus 3 were taken; we will take opening coordinates in the afternoon. Special Finds Find #11 Sieve find Locus 2 107.00-107.20E/42.35-42.55S App. 26.57m A.E. Decorated pottery PM We completed removing the stones from the N wall of the rectilinear structure and worked to remove the remaining olive brown soil of locus 2, which the stones were contained in. Immediately beneath the soil of Locus 2, we uncovered a mottled, compacted surface with visible inclusions of terracotta and plaster. Based on 2015 and 2016 excavations, this likely is the beaten earth surface of the rectilinear structure; it is at app. The same elevation as other exposed surfaces. We continued to use hand picks and trowels to remove the remaining Locus 2 soil. Soil was hand sorted in the trench and then screened through a 1cm gauge sieve. We continued to find moderate quantities of pottery and bone but little tile. Under the easternmost rock removed, on the interface between Locus 2 and the underlying deposit, we recovered a crucible fragment with adhered slag (Find #12). After removing the stones from the eastern edge of the wall and the surrounding soil, it became clear that the easternmost stone is either an outcropping of bedrock that was incorporated into the wall or is imbedded in earlier strata and reused in the wall. We also took opening elevations for Locus 3, which is the western wall of the rectilinear structure. Locus 3 was opened, although we did not excavate in Locus 3 today. Opening Elevations: Locus 3 104.16E/42.70S: 26.47m A.E. 104.55E/42.77S: 26.54m A.E. 104.63E/43.54S: 26.54m A.E. 104.12E/44.15S: 26.38m A.E. 103.68E/44.06S: 26.37m A.E. Special Finds Find #12 Locus 2 108.37E/42.67S 26.59m A.E. Crucible fragment Locus 2 Tile: ⅓ bowl Pottery: 65 sherds Bone: 23 fragments
