Description	Locus 16 is the sandstone step located between the hexagonal pavement of the Shrine Room North Corridor in the west and the floor of the northwest corner of the Shrine Room proper in the east. The step is hewn and dressed and well-preserved. It extends north south, likely marking the point of access between the Shrine Room and its adjacent corridor. No cuts are visible in the step, lessening the likelihood of a doorway in this area.
