STRUCTURE DATING

Abandonment
The absence of refuse in the room fill suggests that the room was probably abandoned at the same time the block was abandoned. The block was abandoned after A.D. 1270, which is the latest tree-ring date for this block.
Construction
One tree-ring date for this structure--A.D. 1064vv. This date is inferred to be from a reused beam, as it is centuries earlier than the other tree-ring dates for the other rooms in this block. Structurally, the rooms in this D-shaped, bi-wall structure appear to have been built at the same time; the latest tree-ring date from roof fall in the bi-wall rooms is A.D. 1260r, which is for Structure 1503. Thus, it is not unlikely that all of the bi-wall rooms in this block were built around or after A.D. 1260.
Remodeling
No evidence of remodeling.
Reuse
No evidence of reuse.
