The Geology of the Great Sphinx of Egypt | Rain Erosion

Recently I’ve watched the outstanding new video from Anyextee, titled "The Sphinx Explained: Origins, Identity and Hidden Entrances", which is arguably the best, unbiased investigation into the Sphinx on YouTube.

It’s an hour and a half in length and if you haven’t seen it yet, you’re in for a treat.

I learned a number of new things in this documentary, including some new historic accounts I had never heard of, and towards the end of the video, Anyextee discusses the rainwater erosion hypothesis as evidence for re-dating the Great Sphinx. As part of this, he mentions the seismic refraction and reflection surveys conducted by Dr Robert Schoch and Thomas Dobecki in the early 1990s. 


As Anyextee said, most alternative researchers and YouTubers rarely mention this latter study – and admittedly that includes me. As someone who has been critical of the rainwater erosion hypothesis in recent months, I have to take a closer look at the seismic survey results. Because I have Masters Degree in Geology I should know a little more than the average person with regards to the subject matter, but I should add I’m no doctor or professor.


So, I did what any good researcher should do and first of all locate the paper by Schoch and Dobecki from 1992 and in this video I take a deep dive into the geology of the Great Sphinx, looking in depth at the rain erosion hypothesis made popular by John Anthony West and Robert Schoch, as well as a detailed look at the seismic survey results conducted by Schoch and Dobecki.


Towards the end of this video, I give my own interpretation of what I think the geology of the Sphinx is showing us, how old the monument is and how I think the monument evolved, including what I think is the possible stage one monument hidden beneath the masonry.
