Here in the foreground we see Special Deposit 99-5, where the floor was missing and three steps led down into a type of drain. The deposit held large shards of earthenware. The next hole is Special Deposit 2000-1, a section of stone floor that had been excavated in pre-Columbian times. This also held thick fragments of earthenware.

Maureen Carpenter investigates Special Deposit 2000-1. There was a layer of deposit under a floor stone here, so we dug down until we hit the large limestone lajas that underlie this entire level of the pyramid. The deposit layer proved to be very thin.

This aperture in the floor was partially surrounded by stucco. The hole is approximately four meters from the sculptured stone platform in the northeast corner of the structure but separated from it by a pier. (See plan, in which the pier is labeled "P4".) The opening is about eight inches in diameter and under eighteen inches deep. Its purpose is unknown, although the stucco seems to have surrounded organic material, possibly wood. It may have served to support a pole acting as a roof support or holding a standard.

Field Supervisor Christopher Powell explains a procedure to his crew members. Chris is working in socks in order not to damage the substantial remains of stucco floor in the western part of the structure. (The eastern part of the building had a floor of stone slabs, but the western part was stucco.)

The northwest corner of Structure XIX is in the final stages of excavation down to the floor level. The piece of the sculptured limestone tablet bearing the Initial Series date from the inscription was discovered near the pier on the left. Just beyond the large rocks remaining in the middle of the floor is a substantial deposit of fragments from the painted stucco panel from the central support pier.

Maureen and Chris work on the wall. Intially it was thought that it was intended as a brace for the roof-support pier seen just to Chris's right. The idea would have been to keep the pier from buckling and twisting, as seems to have happened to the adjacent pier to the west. The wall itself is in turn supported by the stone that Mo is cleaning for photographic documentation in the field report. Ultimately we decided that the wall was used in an occupation period after the collapse of the roof as protection from the elements.
