So, was the blowing sand caused by drought? We also have the interesting fact that many civilizations in the Middle East, Egypt, and probably China experienced major disruptions around 4000 years ago. Sunken Civ brought to our attention that a very large boloid caused crater of that age was found in the Iraq marshes after Saddam Hussein drained them. Such an even could have had world wide repercussions for many years. Has any more work been done to study that crater or its affects?
According to the study, the blowing sand was caused by earthquakes and landslides that exposed more sand to the wind so it could blow.
The area itself has always been extreme desert. The rivers from the Andes could have dried up, and that would have been disastrous for them. But they’d never had any rain in the area, so they wouldn’t miss it.
The area is similar in that regard to Egypt, where it almost never rains.
