Nonstructure 1506, multiple study unit types
About this Nonstructure
Block 1500, west-central portion of site, east of plaza.
Outside of, and adjacent to, the D-shaped building. The test trench (Segment 1) butts up against the exterior face of the east wall.
This nonstructure contains both a layer of construction material used to fill cracks in the bedrock for the construction of the outer wall of the D-shaped structure (Block 1500) and also a layer of secondary refuse above the construction layer. The refuse is inferred to be trash from occupation/use of the nearby structures in Block 1500.
The midden was probably abandoned as a result of the abandonment of the architectural block.
The upper walls of the D-shaped structure collapsed onto the midden material, covering it.

Dating of Midden
One tree-ring date for the refuse stratum--A.D. 1252r. This date appears to be slightly early, because this midden was deposited after the D-shaped structure was built, and the bi-wall rooms appear to have been built around or after A.D. 1260. It is probably therefore safe to infer that this refuse was deposited after A.D. 1260.
