all we ever needed to do to rediscover that knowledge was to measure the height and base perimeter of the Great Pyramid and multiply by 43,200! How l… - Graham Hancock

We know that relatively minor sea-level rises could set off major ice-sheet breakups, and it has been suggested by Stephen Oppenheimer that the tremendous earthquakes caused by isostatic rebalancing at the end of the Ice Age could have stirred up 'mountain-topping superwaves' in the northern regions of the Atlantic and Pacific Oceans. Other than Oppenheimer's own investigations, however, my impression is that while many brilliant individual scientists have studied individual post-glacial phenomena in great depth, very little has yet been done to investigate all these phenomena together as part of a complex system or to consider the effects on the earth and its human population of multiple, interacting cataclysms — floods, lands subsiding into the sea, earthquakes, volcanic eruptions — all occurring at the same time.

a team of Japanese engineers had recently tried to build a 35-feet-high replica of the Great Pyramid (rather smaller than the original, which was 481 feet 5 inches in height). The team started off by limiting itself strictly to techniques proved by archaeology to have been in use during the Fourth Dynasty. However, construction of the replica under these limitations turned out to be impossible and, in due course, modern earth-moving, quarrying and lifting machines were brought to the site. Still no worthwhile progress was made. Ultimately, with some embarrassment, the project had to be abandoned.175

What would have made [seeing Göbekli Tepe from Harran] easier, in antiquity, would have been a tall tower annexed to the temple that once stood here — a temple dedicated to Su-En (usually contracted to Sin), the Moon God of the Sabians. After telling us that there were "powerful images in this temple," the Greek Philosopher Libanius (AD 314-394), describes the tower, noting that "from its top one could overlook the entire plain of Harran."

A team from the Chicago Oriental Institute was about to start a major dig around the ruins of the Grand Mosque in 1986, but it seems that the Turkish authorities insisted on such restrictive practices that the project had to be abandoned. Current excavations by Harran University and the Sanliurfa Museum Directorate show little interest in recovery of substantive remains from the city's pre-Islamic period.
