A very strange and unsolved phenomenon happens at Racetrack Playa, Death Valley National Park, California where rocks leaves a number and length of tracks.
Sailing stones, sliding rocks, and moving rocks all refer to a geological phenomenon
where rocks move and inscribe long tracks along a smooth valley floor
without human or animal intervention. Tracks from these sliding rocks
have been observed and studied in various locations, including Little
Bonnie Claire Playa in Nevada, and most notably Racetrack Playa, Death Valley National Park, California, where the number and length of tracks are notable. At Racetrack Playa, these tracks have been studied since the early 1900s, yet the origins of stone movement are not confirmed and remain the subject of research for which several hypotheses exist.
A CLOSER LOOK:
The stones move only every two or three years and most tracks develop
over three or four years. Stones with rough bottoms leave straight striated
tracks while those with smooth bottoms tend to wander. Stones sometimes
turn over, exposing another edge to the ground and leaving a different
track in the stone's wake.
Trails differ in both direction and length. Rocks that start next to
each other may travel parallel for a time, before one abruptly changes
direction to the left, right, or even back to the direction from which
it came. Trail length also varies – two similarly sized and shaped rocks
may travel uniformly, then one could move ahead or stop in its track.


A balance of very specific conditions is thought to be needed for stones to move:
- a saturated yet non-flooded surface
- a thin layer of clay
- very strong gusts as initiating force
- strong sustained wind to keep stones going
And in some hypotheses:
- ice floes
