Sailing Stones:- Racetrack Playa,Death Valley (Video Included)

The Racetrack playa is 3608 feet (1130 m) above sea level, and 2.8 miles (4.5 km) long (north-south) by 1.3 miles (2 km) wide (east-west). It is also exceptionally flat and level. Racetrack is dry for almost the entire year and has no vegetation. When dry, its surface is covered with small but firm hexagonal mud crack saucers that are typically 3 to 4 inches (7.5 to 10 cm) in diameter and about an inch (2.5 cm) thick.

Sailing stones, sliding rocks, and moving rocks all refer to a geological phenomenon where rocks move in long tracks along a smooth valley floor without human or animal intervention. They have been studied in a number of places around Racetrack Playa, Death Valley, where the number and length of travel grooves are notable. The force behind their movement is not confirmed and is the subject of research. It really is an Unexplained mystery.

 

The stones move only every two or three years and most tracks develop over three or four years. Stones with rough bottoms leave straight striated tracks while those with smooth bottoms wander. Stones sometimes turn over, exposing another edge to the ground and leaving a different track in the stone’s wake. Trails differ in both direction and length. Rocks that start next to each other may travel parallel for a time, before one abruptly changes direction to the left, right, or even back the direction it came from. Trail length also varies – two similarly sized and shaped rocks may travel uniformly, then one could move ahead or stop in its track

    Fascinating, Mags! Some true facts are so strange, that no-one, no matter how vivid their imagination, would ever dream them up. Cheers.

      Hi Mal,
      That is so true, if you didn’t know about Death Valley, you would never believe that rocks could move on their own accord on a flat surface.

    I saw these on the National Geographic Channel some time ago … remended me of the ‘moving rock’ I saw on the beach at Salalah one evening. I’d taken a walk after dinner, and was just about to sit on it to smoke a cigarette (shows how long ago that was! :D) and it MOVED!

    Turned out it was a sea-turtle … and the beach was covered in them!

      “Tuned out it was a sea-turtle” 😆
