Contour map displaying the discrete wet season perimeter time of wetness events on the Stairway at noon on September 24, 2001. Because of the protective shelter, the Hieroglyphic Stairway was assumed to be dry, which is now known to be incorrect, as evidenced by the above map. The black borders within the figure delineate the top step of the Hieroglyphic Stairway and the north and south edges of the Stairway balustrade.
