There you are, just minding your own business. And all of a sudden, a helpful sign tells you that there is a monkey. The sign doesn't tell you where the monkey is, just that it's around. And that it bites. And if you try to fight, you can't win. That's just one of the signs. What else is out there?

A century ago, miners working in California's Death Valley reported seeing boulders on the desert floor with long trails behind them — as if the stones had been pushed across the sand. But despite 60 years of trying, no one ever saw what moved them.
Now scientists think they've solved the mystery of the "slithering rocks of Death Valley." Using GPS tags pasted to the boulders, and a video camera, a geologist from Scripps Institution of Oceanography and his engineer cousin have evidence that broad, jagged panes of melting ice push the stones across the desert, nudged in one direction or another by the breeze. The team details their results in the current issue of the journal Plos One.
