Dating of Construction

Surface appears to have been constructed when the adjacent roomblock was constructed; architectural style of the masonry appears to be Pueblo III (A.D. 1150-1300).

Dating of Abandonment

Pottery sherds found on this surface are of types that were produced during the late Pueblo II and the Pueblo III periods (between A.D. 1140 and 1300), and were probably deposited sometime during the occupation of the adjacent roomblock.
