Re: clear rock. I saw some once and was told that it was formed by lightning striking sand. I didn't really believe the person. Any truth to existence of rock formed in this way?

I think that's a way some guy gets money in Sweet Home Alabama.
It is called fulgurite.
All the fulgurite I've seen is dirty, because although it cooks the sediments where the lightning strikes, all the other surrounding sediments nearby melt slightly and adhere to the main body. So, the only way to get it clear is to sand and clean around it. Most fulgurite are really small and would make this hard, and not worth it because cool structures wouldn't be preserved. You might have this one spectacular one you could do it on...but why would you ruin it?
