"Beneath the mound that is the remains of the central temple are the two rooms of the lower range that run north-south, and you can reach the eastern room through an eastern doorway by an easy trail from the back (south side) of the building.
There are some remnants of paint in the eastern room, and in one area there is the upper part of a figure in profile with an elaborate headdress (difficult to discern). Originally there were painted capstones, one each in the eastern and western rooms under the central temple, but both have been removed. Fortunately they were well documented by scholars before their disappearance."
