Tim Cullen at Malaga Bay posted up another thought provoking comment concerning Arabia, and used a photo of a Tell. On seeing this I immediately recognised the geological implications, (this one being Tell Barri in Syria).

So here is a photo of a typical Mesa in an arid environment.
A tell is an artificial hill created by many generations of people living and rebuilding on the same spot. Over time, the level rises, forming a mound. The single biggest contributor to the mass of a tell are mud bricks, which disintegrate rapidly. Excavating a tell can reveal buried structures such as government or military buildings, religious shrines and homes, located at different depths depending on their date of use. They often overlap horizontally, vertically, or both. Archaeologists excavate tell sites to interpret architecture, purpose, and date of occupation. Since excavating a tell is a destructive process, physicists and geophysicists have developed non-destructive methods of mapping tell sites.
No it’s not: a Tell is similar to a Mesa – a remnant of an eroded larger urban area. What caused the implied massive erosion? A large flood or deluge could do it. Instead of looking for a flood layer in the Tell, or elsewhere, the arkaeologists missed the forrest for the trees. The deluge was post the settlements remaining as a lonely hill.
Update: More likely the Mesa/Tell was left over from incomplete “electro-machining” by planetary scaled plasma discharges between the Earth and some external body via the ionosphere.
