Stratigraphic Summary

The purpose of this trench was to expose sections that would be a coninuation of other known tratigraphy, particularly that in the south baulk of T-22 W extention and that in the east baulk of T-25 Y-Z/13-20.  This trench achieved those goals, but only in a mixed form.

H-I/23-24

This area was excavated first because it was the backfill of T-6b. The fill is clearly visible in the north and south baulks. Interestingly, although Gantz reports excavating down to natural soil (TGIII p.45), this is clearly not the case. Medium to dark brown clayey soil with carbon and ceramic material is visible beneath the fill in both baulks. Several additional centimeters were excavated. They contained little to no material. The soil at the bottom of the trench

is beginning to take on characteristics of galestra. Several centimeters still need to be removed from the area.

In the east baulk at H-I/24 the baulk reveals a medium brown clayey topsoil (10YR 5/3 brown), underneath which is a less clayey soil (2.5Y 6/3 light yellowish brown) Underneath that and confined to the I/24 meter is a reddish burn that does not appear elsewhere in the trench. Finally there is a sterile clayey soil (2.5Y 7/4 pale yellow). This area needs to be excavated next year (H-I/25-27) to look for a continuation of the wall found in I/20-22 (see below).

H-I/20-22

This is the area north of the wall. The stratigraphy of the north, south, and east baulks is somewhat inconsistant. The western two meters have a relatively heavy burn layer, for example, while H-I/22 does not.

The basic stratigraphy of the west baulk consists of a clayey topsoil (10YR 5/3 brown) containing little material. Underneath is a lighter clayey soil, also with little material (2.5Y 6/3 light yellowish brown). This layer overlies a burn layer which produced significantly more material than any other area of the trench: plaster, tile, and pottery. The soil color is 7.5YR 5/2 brown. Underneath this layer is an almost sterile 2.5Y 7/4 pale yellow soil. It is not natural soil. More excavation must occur to expose natural soil.

The stratigraphy of this west baulk was one o the goals of the trench. Because the east baulk of T-25 Y-Z/20 has since been eiscovered to be T-6a backfill, it is currently the only stratigraphic record for this meter of the site. The stratigraphy of the north baulk is basically the same as that of the west, except that the burn

layet is thinner and sits at a slightly higher level than in H-I/20. It is not present in H-I/22. Also there are medium gray pockets very close to the bottom layer of soil, 10YR 7/3 very pale brown.

I/20-22, J/20-22 South baulk

The wall is currently the uppermost feature of this baulk, although it was covered by the same topsoil as elsewhere in the trench.

The wall consists of one course of stones, undressed and loosely placed. No foundation trench in discernible in the west baulk. Several aspects are curious: there was little material near, over, or between the stones, and there were no associated floors. The wall sits at a higher elevation that found in T-25 U-V/17-23. There is no mention of this wall in the ntoes for T-6b (TGIII) and it is possible that it was removed during excavation. There is one stone that forms a cross wall, and the recommended

course of action is to continue excavating in H-I/19, J/20-22, AND j/25-27.

Under the wall are several small stones and there is stratified soil beneath it. The first is a clayey gray brown, which sits atop a dark clayey brown soil (2.5Y 4/3 brown), whih appears in two places on either side of a rectangular area of light friable yellow soil (2.5Y 8/3 light brown), which has almost nothing in it but is not galestra. The burn layer is not easily discerned in the south baulk.

On the south side of the wall in J/20-22 was the topsoil (10YR 5/3 brown), which had almost no material.
