Okay, I'll try playing Nancy Drew! :lol

What if it has something to do with Death Valley being the lowest point, below sea level, in the U.S.? Not sure why, but that popped into the ol' noggin'!

You know the crop circles are made through sound that can't be heard by humans, it's beyond our normal range. This is why the wheat stalks are not harmed. What about animals hearing? Has anyONE looked at their reactions to the stones? Have they done the time-frame videographing like in the way they capture a flower in bloom? :)

I love spiralling! :D
