LOCATION Found in 1972 by the French Archaeological Mission. The butt was in place in the temple of Structure 05-1; the carved portions were in rubble at the top of the mound and at the foot of the west side. Now in the site museum.
CONDITION Broken into several fragments, six of which were found. These compose the upper two-thirds of the shaft and the connecting lower part. Part of the front carved surface is well preserved, and part eroded or split off. The inscribed left side is fairly well preserved.
MATERIAL Yellow sandstone.
SHAPE A flat slab with well-dressed face and sides. The sides are parallel for fourfifths of the height, then converge slightly towards the rounded corners of the top. The butt is trimmed square.
CARVED AREAS Front and left side.
