Descending Passage
Potomac Avenue (in red on the map below) runs from the extreme east of the map to the extreme south, at the same angle as the descending passage of the pyramid. This is the best "fit" of any map element with a feature of the pyramid cross-section image.
The Subterranean Chamber
The Subterranean Chamber is the most roughly cut chamber in the Great Pyramid, and lies directly beneath the line where the King and Queens' Chambers meet, that is the southern wall of the QC. In order to enter the pit, you follow the 345 feet long descending passage, then a smaller 29 foot level passageway. One of the main questions surrounding the Washington DC landscape is, if elements in the map do correlate to features in the pyramid (cross-section image), what is there that correlates with the Subterranean Chamber, which would lie under the Potomac River close to Ronald Reagan Airport, and not very far from the Pentagon. Note that on the southern end of the chamber there is, what has been called, a dead-end passageway, some 60 feet long. As you can see, this is long enough for the whole of the subterranean passageway to completely cross the Potomac River, if one were to exist there. Compare the thee points of land in the modern map below to the planning map above, in order to get an idea of how much the area has changed. These have been labeled G, H and B for Gravelly, Hains and Buzzard Points. Underground City As we suggested earlier, the chamber, were it to exist, would be quite near the northen end of the airport; just off Gravelly Point. Note, in the image below, the proximity to the Pentagon (in red), and the location of Crystal City. Looking on a Rand-McNally road map for Washington, D.C., you will see (in the location where we have put the name Crystal City in yellow letters) in red lettering, "Crystal City Underground Shopping Center". We find Crystal City listed on an aswers.com webpage that answers the question, "What is an underground city?". The page calls Crystal City, an unincorporated residential and commercial area next to Washington National Airport, which features an extensive underground city connecting its hotels, office buildings, and apartment towers.
