The ceramic scatter in L507 with the three polishing stones (Ar/Ge.T19.507.L.01-3)is located 67 cm meters below the datum (2282.81 m). Roman took a macro-botanical sample from the scatter 9Ar/Ge.T19.507.MB.01). After photographing the scatter, we pulled the ceramics and started a new locus (L509).
The soil in L509 is quite mottled, ranging from yellow, yellow-brown, brown, to brown-black, but is generally loose and moderately granular. We found a small polishing stone in L509 (Ar/Ge.T19.509.L.01). In the southern half of L509, there is a black stain, near some disintegrated, red fired clay. The area may be a pit, but it is very irregular in shape and is now L510. The soil in L510 is very loose, black, and much less granular than the surrounding soil. Roman took a soil sample (Ar/Ge.T19.510.MB.01) from the bottom half of Locus 510 (at 79 cm below the datum, 2282.69 m), as the top half had been disturbed by ants. Further down in L509, we came down on a horseshoe of burned clay with dark black soil in the center (L511). Roman took as soil sample (Ar/Ge.T19.511.MB.01), and we discovered that there were large pieces of ceramics lining what appears to be a hearth feature. It seems likely to me that these two feature (L510 and 511) are in a second EBA floor, beneath the first one where the ceramic scatters were found, in part because of the depth between them, as well as the different soil matrices characterizing the loci.
