What an eerie and mysterious place this is. I heard about it when I was young in a tale that I was seemed beyond reach to authenticate. I stuck in my mind all this time, and I finally went to go visit this remote spot in Death Valley.
These huge rocks slowly move across the desert and leave a dried bobsled-trail path behind them. The ground is cool with a very light dusting of sand. I was barefoot and it felt like walking in the tiled courtyard of an Italian villa. There are hundreds of these rocks all over this dried lakebed. They all move in one direction or another, often towards an even bigger, anchored rock in the center of the lakebed.
I felt like if I got very very close to the rock and sat very very quietly, maybe I could see it move or pull towards me a little but I never did.
