Five things that modern science cannot explain:

25. Thank you.

Your post is simple to understand, lacks the rudeness of some other replies found here, and even admits that there is a mystery or two that still remain.

I also knew that there was a logical explanation for the "moving stones" (which in some cases are more like moving boulders.) But I think that your explanation was what I was told about twenty years ago, by a geologist who loved to watch those things glide across the desert floor.

A narrator for a TV show on the phenomena stated that "no one has ever seen the stones move" and that the reason people knew they moved was because of the trails they leave in the sand.

But this geologist had home movies of them moving. And of course, he went down to Death Valley in the winter, so I think that is what the TV show producer didn't realize - he had only talked to summer inhabitants of Death Valley.
