No, not the beer.
Irrelephant made an offhand comment on my last post about stones in the desert rolling by themselves, which I had never heard of, so I Googled and came up with these rather amazing images.
This is a real phenomenon in Death Valley. It is less well understood than the snow rollers of my last post. The explanation on the page where I found the pictures says "studies suggest a combination of 90mph winds, ice formations at night and thin layers of wet clay on the surface of the desert all help to push them along." The fact that the stones are rolling in different directions seems to pour some doubt on wind being much of a factor, but I'm no scientist.
Pretty cool, regardless. Sometimes it seems like nature is just fucking with us.
