What is the leading theory on sailing stones?
In 2014, scientists were able to capture the movement of the stones for the first time using time-lapse photography. The results strongly suggest that the sailing stones are the result of a perfect balance of ice, water, and wind.
How do sailing stones work?
Sailing stones, or moving rocks, are any composition stones that move on the flat mud surface and leave a trail behind them. Their movement is caused by thin ice sheets the stones are frozen into. Sailing stones move due to ice rafts created in winter after the heavy rains.
Who Solved the sailing stones mystery?
Sailing stone tracks. Image via PLOS ONE. How could rocks – driven by some unseen force – slide across the ground, leaving behind a trail? At Racetrack Playa, a dry lake bed at Death Valley National Park in California, it was a long-standing mystery that was finally cracked in 2014 by two cousins.
How fast do the sailing stones move?
These thin floating ice panels, frozen during cold winter nights, are driven by light winds and shove rocks at up to 5 m/min (0.3 km/h; 0.2 mph). Some GPS-measured moves lasted up to 16 minutes, and a number of stones moved more than five times during the existence of the playa pond in the winter of 2013-14.
How much do the sailing stones weigh?
Littered across the surface of this dry lake, also called a “playa,” are hundreds of rocks – some weighing as much as 320 kilograms (700 pounds) – that seem to have been dragged across the ground, leaving synchronized trails that can stretch for hundreds of meters.
Can you have fire in Death Valley?
Remember that within Death Valley National Park, campfires are allowed only in provided fire pits within developed campsites. Backcountry campfires are not allowed at any time of the year, with or without a campfire permit.
What’s the coldest recorded temperature in Death Valley?
The valley’s lowest temperature, recorded at Greenland Ranch on January 2, 1913, was 15 °F (−9 °C).
Can I sleep in my car at Death Valley?

Sailing stones, also known as sliding rocks, walking rocks, rolling stones, and moving rocks, are a geological phenomenon where rocks move and inscribe long tracks along a smooth valley floor without human or animal intervention.

What causes stones to sail on Ice?
A combination of this slick melting ice and a particularly slimy cyanobacteria that live in the soil, surface winds push these stones along the surface, leaving their signature traces. What causes stones to sail? What weather phenomenon are necessary for this to happen?
