I don't believe it either. What kind of rain bleaches stone? The stain is lighter than the stone, if it were darker I'd call it a stain. But for now I'm calling it bleached.
Besides, there are many sandstorms every year at Giza, more sand is blown in than water pours in. By the time that first torrential rain came along how much sand do you think had accumulated in the shaft? Would have to be one hell of a downpour to clear the accumulated sand. There was a sandstorm when Gantenbrink was clearing this shaft dumping even more sand into an already clogged shaft. You would have to conclude that there were no sandstorms to choke the shaft in order for rain to flow freely and abundantly through the shaft making the white stain. And why would the rain stop inches from the floor?
I have to chuckle at you guys who live in humid wet climates. Condensation? The only condensation you'll find in the desert is on your forehead as you sweat to death.
I've tried to point this out before, but building a structure like this in a sea of sand with sandstorms is a major problem. Every time the wind kicks up there would be a layer of sand on everything that would have to be cleared if you want to maintain that 1/2" of level and joints as precise as we see. They would have needed a crew just to continually clear sand. They built upon a bedrock foundation so that the building wouldn't shift. Which means they were fully aware of the problems of a soil or soil/concrete foundation. Having this much construction knowledge they wouldn't make complicated shafts that would easily fill with sand and stones. It would defeat whatever purpose the shafts had. If they were intended as water conduits a once in 20yr torrential rain would accomplish what?
Conclusion: the sand was not there when the pyramids were built.
