1. What Are Death Valley Traveling Rocks?
Death Valley’s traveling rocks are stones found on the surface of Racetrack Playa, a dry lakebed, that appear to move across the flat terrain without human or animal intervention. These rocks, ranging in size from small pebbles to large boulders weighing hundreds of pounds, leave visible trails in the playa’s surface, creating a mysterious and intriguing landscape.
What is Racetrack Playa?
Racetrack Playa is a flat, dry lakebed located in Death Valley National Park, California. It’s renowned for its incredibly level surface and the enigmatic phenomenon of the moving rocks.
How big are the rocks?
The rocks vary significantly in size, ranging from small pebbles to large boulders. Some of the larger rocks can weigh up to 700 pounds (320 kilograms).
What are the trails made of?
The trails are formed as the rocks move across the surface of the playa, leaving impressions in the soft mud. These trails can vary in length and direction, sometimes stretching for hundreds of meters.
2. Where Can I Find the Sailing Stones in Death Valley?
The sailing stones are primarily found on Racetrack Playa in Death Valley National Park. To get the best view of the rocks and their trails, head two miles south of the Grandstand parking area and walk at least half a mile toward the southeast corner of the playa.
How do I get to Racetrack Playa?
Racetrack Playa is located in a remote area of Death Valley National Park. Reaching it requires driving on a long, unpaved road that is best suited for high-clearance vehicles with heavy-duty tires.
What should I be prepared for when visiting the Racetrack?

Yes, another accessible location to observe the tracks of sliding stones is the Bonnie Claire playa east of Scotty’s Castle, between the park boundary and Highway 95. This area is administered by the Bureau of Land Management and also exhibits evidence of sliding stones.
3. What Causes the Death Valley Moving Rocks to Move?
The movement of Death Valley’s rocks was a long-standing mystery until a 2014 study published in PLOS ONE provided a definitive explanation. Researchers discovered that a rare combination of rain and wind conditions, along with the formation of thin ice sheets, are responsible for the rocks’ movement.
How do rain conditions contribute to the movement?
A rain of about 0.5 inches wets the surface of the playa, creating a firm but extremely slippery mud surface.
What role does wind play in moving the rocks?
Strong winds, typically 50 mph or more, can skid the large boulders along the slick mud surface.
What is the ice sheet theory?
The research team found that the playa fills with water, which freezes during cold winter nights to form thin sheets of “windowpane” ice. On sunny days, this ice breaks up into large floating panels that are driven by light winds, pushing the rocks in front of them.
4. What Was the Research That Finally Solved the Mystery?
A team led by paleobiologist Richard Norris from Scripps Institution of Oceanography, UC San Diego, conducted a long-term study starting in 2011. They installed a high-resolution weather station and fitted 15 rocks with custom-built, motion-activated GPS units to monitor the rocks’ movement remotely.
How did the researchers monitor the rocks?
The researchers used GPS units attached to the rocks and a high-resolution weather station to collect data on wind speed, temperature, and other environmental factors.
What were the key findings of the research?
The study revealed that the rocks move under light winds of about 3-5 meters per second (10 miles per hour), driven by thin ice sheets less than 5 millimeters (0.25 inches) thick.
What was surprising about these findings?
Previous theories had proposed hurricane-force winds or thick sheets of ice as necessary for the rocks to move. The study showed that much gentler conditions were sufficient.
5. What Were Some of the Previous Theories About the Moving Rocks?
Before the 2014 study, numerous theories attempted to explain the movement of the rocks. These included hurricane-force winds, dust devils, slick algal films, and thick sheets of ice.
Why were these theories ultimately disproven?
The 2014 research provided direct observational evidence that contradicted these earlier theories. The rocks were found to move under conditions that were far less extreme than previously believed.
What is the dust devil theory?
The dust devil theory suggested that strong, rotating columns of air could push the rocks across the playa.
What is the algal film theory?
The algal film theory proposed that a slick layer of algae on the playa surface could reduce friction, allowing the rocks to move more easily.
6. How Fast Do the Death Valley Sailing Stones Move?
The rocks move very slowly, only a few inches per second (2-6 meters per minute). This speed is almost imperceptible at a distance and without stationary reference points.
How long do the rocks stay in motion?
Individual rocks can remain in motion for anywhere from a few seconds to 16 minutes.
Can rocks move simultaneously?
Yes, researchers observed rocks three football fields apart beginning to move simultaneously and traveling over 60 meters (200 feet) before stopping.
Do the rocks move frequently?
No, the rocks move very rarely. There is evidence suggesting that the frequency of rock movement may have declined since the 1970s due to climate change.
7. What Impact Does Climate Change Have on the Moving Rocks?
Climate change may be affecting the frequency of rock movement. The phenomenon requires cold nights to form ice, and as temperatures rise, these conditions may become less frequent.
How has the frequency of rock movement changed over time?
There is evidence suggesting that the frequency of rock movement has declined since the 1970s, possibly due to warmer temperatures.
What evidence supports this claim?
The last suspected movement before the 2014 study was in 2006, indicating that rocks may move only about one millionth of the time.
How might warmer temperatures affect the playa?
Warmer temperatures could reduce the formation of ice sheets, which are essential for the rocks to move.
