Sand Canyon Pueblo

The absence of refuse in the room fill suggests that abandonment occurred sometime after A.D. 1270, the latest tree-ring date for this block.

One tree-ring date for this room--A.D. 1224++vv. This date indicates only that the room was constructed after that year. 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 cutting date of A.D. 1260, which is for Structure 1503. Thus, it is likely that all of the bi-wall rooms in this block were built around or after A.D. 1260.

There are two prepared floors in this room; no means by which to date the second prepared floor.

An ephemeral surface on a thin layer of washed-in sediment could be interpreted as the last use of the room, or alternatively, as reuse of the room. There is no way to date this use.
