Description	A continuous vault springer, carried on the east ledge and vaulting wall built up against the west face of the middle cryptoporticus wall of the East Colonnade, as described above. The vaulting is fairly well constructed of squared sandstone blocks, and is preserved in most places to two courses. Its underlying relationship (or really, the underlying relationship of the whole wall complex of Loci 14, 19, and 20) is unknown since the bottom of the complex was not reached this season. The south portion has been badly damaged by column collapse (Locus 16).
