Starting from the docking area at the Unfinished Obelisk Quarry a series of shallow seismic profiles were run that have defined the location and dimensions of the channel that was used to transport obelisks to the Nile River. Besides the profiles nearest the quarry showing how the obelisks left the site, a key new set of seismic profiles located approximately halfway to the Nile conclusively located the channel confirming that it turns northward on its path to the Nile. The channel depth was found to steadily increase away from the quarry from a depth of approximately 2.5 m in the bedrock near the quarry to approximately 7 m at the mid-way site. The width of the channel is approximately 30 m. Grafitti on the walls near the quarry depicts sea life likely indicating the connection between the obelisk quarry and the Nile that transported them to sites at large distances downstream from Aswan. The logistics of how the massive obelisks were transported to the Nile remain to be conclusively determined. The seismic surveys were carried out using a digital recording system with 24 geophones spaced typically at 2 m intervals and a Betsy Seisgun to detonate shotgun blank sources located at both ends of each profile. Examples of the seismic record sections along with their 1D-2D Pand S-wave velocity profiles and interpretations will be presented along with illustrations of the location of the lines. |
