Drilling to Save Aswan Obelisk Quarry
The Ancient Egyptians are still marveled at today for some of their enduring hard-rock creations. Of course everyone thinks of the Sphinx and the Great Pyramids, but perhaps just as impressive if not more impressive were the gigantic obelisks that were quarried and somehow transported into place. There is work underway to preserve a rare archaeological site, a granite quarry with a large unfinished obelisk near Aswan.
Archaeological evidence combined with some shallow seismic refraction surveys and bore holes confirm the finding of a canal believed to have been used to transport these obelisks to the Nile River during flooding. However, dewatering will be needed to excavate these canals to verify these claims. Another problem is the salt deposits that are slowly destroying the quarry. National Driller Magazine is the location of this interesting article. Link after the break. (Photo by Son of Groucho)
