Description	A wall built from a combination of dressed ashlars, hewn blocks, and snecking stones laid in five courses using wet-mortar. Although the area to the north of the wall remains unexcavated, it appears that the wall is compounded of only one row. The level of the top of the wall is contiguous with the Locus 5 leveling course exposed to the north. The south face of the sturdy wall is even, and shows no indications of repairs. The ashlars and hewn blocks appear to be sandstone¾of varying degrees of hardness. The snecking components utilized both naturally flat and roughly shaped field stones. Ten ashlars distributed thoughout the wall face exhibit Nabataean dressing marks, all of which are executed using short rather than long strokes; nine of these blocks are placed so that the dressing marks are angled in the same direction, while on the tenth the marks angle the opposite direction. Both the irregular distribution of the dressed blocks and the variation in the dressing marks suggests that the ashlars may be in re-use. A long hewn block in the topmost course at the west edge was shaped to also serve as the lowest course for construction of the vault (Tr. 97, 2004, Locus 14) in the west Middle Pier Wall (Tr. 97, 2004, Locus 11). This clearly demonstrates that the construction of the wall and the vaults between which it spans was contemporary. During excavation a coin was found resting on the third block east of the Middle Pier Wall in the top course.
