That is what I had thought.
Maybe patrickgiles has some evidence of more intensive rain in that region during that time period?
You know, I could cite all kinds of data that proves rainfall. However, it is more important to realize what happened when it rained on a pyramid complex. If it rained one inch on a large pyramid during a torrential downpour, the amount of rain captured would have been incredible. One inch equaled nearly 600,000 gallons of water, and all of it was deposited at the base of the pyramid, where it was held within stone block enclosure walls. I challenge anyone to find a study that cites that there were any drainage holes in the enclosure walls. In fact, all Egyptologists agree that there were no openings whatsoever except in on place. I hope the learned are listening right now. The only opening in the wall leads directly into the so-called mortuary temple, and this has to be considered. There was only one exit in the mortuary temple. One only. No windows. Where did the water go? It went out the exit and flowed into a long corridor called a causeway. Its so obvious to me, of course. It rained enough to cause great flooding problems on the Giza Plateau according to the research reports of the Oriental Institute. Check it out.
