[68:173] - Sixty-five meters up the southern shaft of the Queen's Chamber is a miniature portcullis slab discovered by a robotic camera in 1993. Attached are two copper fittings, one broken. This area of the shaft is lined with Tura limestone, which is typically used in pyramids only for lining chambers.

[18:103] - In the King's Chamber all of the stone joints are very tight except in the lower left-hand corner of the west wall. Here the joints are larger than normal and covered by mortar. This is a strong indication of an opening to another chamber or passage. The Egyptian government has refused requests for further exploration.

[18:104] - In 1986 a French team using microgravimeter equipment detected small hidden cavities behind the west wall of the horizontal passage to the Queen's Chamber. They were permitted to bore a 1" diameter hole and found a cavity filled with sand. They were not permitted to dig or tunnel for further investigation.

[18:105] - The cavities in the horizontal passage to the Queen's Chamber correspond to two floor stones in this passageway with joints perpendicular to the rest of the joints in the floor stones. This type of indicator can also be found at the junction of the descending and ascending passageways.

[18:276] - About 70 feet along the north side of the Great Pyramid from the northeast corner is a 4x10 ft stone sunk into the foundation at an angle. The joints are very precise and this is the only stone in the foundation perimeter not at a right angle to normal construction. It would have been covered by the mantle but is now accessible since the mantle is gone. It is very likely an entrance. No further investigation has been done.

[14:72] - It has long been believed that the Sphinx had subterranean tunnels leading to each of the three major pyramids. In October, 1994, a passage leading to a subterranean area beneath the Sphinx was re-discovered. Further investigation is expected in February of 1995.

[88:101] - In 1987 a Japenese team used an electromagnetic wave method to search for cavities in the Great Pyramid. They identified a cavity under the horizontal passage to the Queen's Chamber about 1.5 meters beneath and extending for 2.5-3.0 meters in depth. They also identified a cavity behind the western part of the northern wall of the Queen's Chamber. They identified no cavities within the King's chamber, possibly due to the denser granite walls. Three potential cavities were identified in the area of the Sphinx.

[117,117] - In 1988 a Japanese team lead by Professor Yoshimura detected a cavity off the Queen's Chamber passageway very near to where the French team drilled in 1986. They also detected a large cavity behind the NW wall of the Queen's Chamber and a sign of a tunnel outside of the pyramid, which appeared to run underneath the structure. Egyptian authorities intervened and halted the project. The team has not been allowed to return to complete the project.

[117,50] - In October of 1992, Professor Jean Kerisal was part of a team conducting ground penetrating radar and microgravimetric measurements in the Pit and horizontal passage connecting the bottom of the descending passage. Results in the Pit were not conclusive but were extremely promising in the horizontal chamber. A structure was detected under the floor of the horizontal passage. A second structures was detected on the western side of the passageway about 6 meters before the entrance to the chamber. Soundings seem to indicate a vertical shaft 1.4 x 1.4 meters and at least 5 meters deep very close to the western wall of the passage. This could be either a natural chamber in the limestone or a completely separate passageway system.
