Chacmultun: The Palace [February 16, 1997]
The west side of the Palace has a stairway leading to the roof, with an arched passageway underneath the stairway. Pollock notes that there is a small ceremonial platform or altar on the roof of the first story, and adds that a second story was presumably planned but never built.
