I know that for some of you, seeing the tracks across the playa surface can only mean one place on the planet: Racetrack Playa in Death Valley National Park. For years and years geologists and others noted the strange trackways made by pebbles and boulders and pondered how in the world they happened. There have been the "boring" scientific hypotheses involving wind, water and ice, and the more exotic fringe ideas like weird magnetic currents and aliens. I took the picture, but I've never been to Racetrack Playa and therefore am not guilty of tampering with the stones (the National Park Service and geologists take a very dim view of such things). It turns out the strange sliding stones have been found in other places. I know of at least three of them.

The greatest irony of the mystery of the sliding stones is that they might soon no longer move at all. As the climate changes and warms over the coming decades, the required conditions, particularly that of ice formation, will no longer exist.
