These extraordinary pictures reveal a bizarre event that is puzzling the science world - rocks that glide across the desert.
Amid the eerie silence and the 50C heat of California's Death Valley these giant boulders appear to move smoothly - and unaided - across the desert.
The rocks, some as heavy as 17 stone, edge along in bizarre, straight-line patterns across the ultra-flat surface of the valley. They can travel more than 350 yards a year.
Scientists believe the phenomenon is caused by a coming together of specific weather conditions.
Studies suggest a combination of 90mph winds, ice formations at night and thin layers of wet clay on the surface of the desert all help to push them along.
Photographer Mike Byrne, 40, has spent years documenting the stones' mysterious movements.
