 Unlike most such buildings in the Peten, though, the Temple of the Masks has a large staircase outset, near the top of the stairs.Similar outsets are seen are Altun Ha (Pendergast 1979, 1982) and Kakabish (Guderjan 1996).The facade of the outset is adorned with a complex five paneled, deep relief stucco frieze which included at least two and probably three anthropomorphic masks.
