ceiling slabs near the south wall.

Here too are shafts, very similar to those in the Queen's
chamber, which lead out to the two sides of the pyramid at
heights of 71 and 53 meters. The northern channel is only 5" high
x 7" wide and ascends at an angle of approximately

31° and is 235' in length. The southern, channel measures
about 8" high x 12" wide, rises at an angle of 45° and is 175' in
length. Presently there is a ventilation fan fitted into the southern
shaft and this regulates the moisture in the chamber, minimizing
the damage caused by the moisture produced by the breath and
sweat of visitors.
