What causes the rocks in the Death Valley to move?
There had to be a shallow layer of water in the dry lake bed and nighttime temperatures cold enough for the formation of a thin layer of ice. On sunny days, melting caused the ice to break into large floating panels that, driven by light winds, pushed against the rocks to move them, leaving tracks on the desert floor.
Do rocks really move in Death Valley?
Once they reach the level surface of the playa, the rocks somehow move horizontally, leaving perfect tracks behind them to record their path. Many of the largest rocks have left behind trails as long as 1,500 feet, suggesting that they’ve moved a long way indeed from their original location.
Why sailing stones move?
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.
Does anything live in Death Valley?
Despite the low precipitation and extreme summer temperatures, Death Valley is home to many diverse species, several of which are endemic (found nowhere else in the world).
Can rocks move by themselves?
Sailing stones (also called sliding rocks, walking rocks, rolling stones, and moving rocks) are part of the geological phenomenon in which rocks move and inscribe long tracks along a smooth valley floor without animal intervention.
What causes rocks to slide across a playa lake bed?
As cousins Richard Norris and James Norris watched, a light wind began moving huge floes of ice across the surface of the water and into rocks weighing up to 200 pounds. Propelled by the ice masses, the rocks began to slide across the slick, muddy bottom of the normally dry lake bed, known as the Racetrack playa.
Can stones move by themselves?
Who discovered the sailing stones?
But in December 2013, Norris and co-author and cousin Jim Norris arrived in Death Valley to discover that the playa was covered with a pond of water seven centimeters (three inches) deep. Shortly after, the rocks began moving. “Science sometimes has an element of luck,” Richard Norris said.

Death Valley National Park. The moving rocks of the Racetrack. Photo by Jeffery Aiello. Racetrack Playa is home to one of Death Valley’s most enduring mysteries. Littered across the flat surface of this dry lake, also called a “playa,” are hundreds of rocks that seem to have been dragged across the ground.
What is the mystery of the sailing stones in Death Valley?
Mystery of Death Valley’s ‘Sailing Stones’ Solved. Some researchers thought that dust devils might move the rocks, some of which weigh as much as 700 lbs. (318 kilograms). Other researchers believed the strong winds that frequently whip across the vast lake bed could cause the rocks to slide across the ground.

Why do rocks float on the mud at Death Valley?
Lorenz’s research team calculated that under certain winter conditions in Death Valley, enough water and ice could form to float the rocks across the muddy bottom of Racetrack Playa in a light breeze, leaving a trail in the mud as the rocks moved.
