( http://heritage-key.com/blogs/keith-p... ) Dr Zahi Hawass and Dr Mark Lehner talk about the latest conservation tests being carried out at the Great Sphinx, Giza, to test whether this iconic Egyptian landmark is at risk of a rising water table. Assisted by the Cairo University, the team are making holes around the Sphinx to check the porosity of the limestone underneath, as well as a side-benefit of being able to test the theories of whether there are hidden chambers and tunnels underneath.
