Death valley is famously known as the hottest place on earth with many of mysteries, sailing of stone is one of the petal in this flower
Death walley is the driest place in north America, and home to the strangeness seeming playa known as the racetrack playa. Here stones sail leaving traces in the mud behind . Many of them leave traces of 1500 m.
Researchers claim that a rare combination of Rain,water and wind conditions enabled the rocks to move
A rain of 1/2inch will wet the surface of playa, then the surface becomes extremely slippery and reduces the friction between the stones and muddy surface strong wind of 50 mph ,skid the large boulder
The problem with wind moving the rocks is that many of the rocks weigh more than 300 kilograms and are embedded a few inches into the mud of the playa. It is unlikely that wind alone could move these heavy rocks
Richard Norris and his cousin James norris started research and began studying the region in 2011 by setting up weather station, time-lapse cameras and dropping of rocks loaded with GPS trackers
After 2 years both of them travelled to racetrack playa and they were able to capture the movement of the stones for the first time using time lapse photography
And the real reason behind sailing of stones came forward
In the winter, rain water formed a pond that froze overnight and thawed next day creating a vast sheet of ice that started melting because of sunlight .Driven by light wind this sheet broke up and accomodate behind the boulder,slowly start pushing them forward
These boulders only move once every two or three years and most tracks last for three or four years
In the statement,Richard Norris Said ,
Science sometimes has an element of luck. We expected to wait five or ten years without anything moving, but only two years into the project, we just happened to be there at the right time to see it happen in person.
