Sailing Stone
This is one of the sailing stones at the racetrack playa in Death Valley. The racetrack is reachable by car but be prepared for 27 miles of very rough road. I geotagged this photo, click on the map link in the bottom right of this page to see its location.
Racetrack playa is an amazing place and if you go to Death Valley I really encourage you to go check it out. Original public domain image from Flickr
