# Seismic investigations in the vicinity of the Great Sphinx of Giza, Egypt

Thomas L. Dobecki, Robert M. Schoch, 1992. _Geoarchaeology 7(6): 527-544_.

Seismic refraction profiles around the Sphinx reporting a weathered low-velocity layer beneath the ditch floor, deeper on the sides and front than at the rear, read by Schoch as evidence of long exposure.
