They Caught Death Valley's Moving Rocks on Camera, and What Happened Next Is Insane...
For decades, rocks in Death Valley appeared to move across Racetrack Playa on their own, leaving enormous trails behind them.
Scientists eventually caught the process in action. GPS instruments and cameras showed that shallow water, freezing nights, thin sheets of ice and light winds can combine to slowly push rocks across the muddy lakebed. During one 2013 event, more than 60 rocks moved.
But there’s still a catch: researchers never directly observed some of the largest boulders moving. Even the National Park Service notes that this part of the mystery remains open.
In this DiscoverTube investigation, we look at how the mystery was solved, what the experiment actually proved, and what scientists still don’t know.

Video Summary
AI GeneratedScientists have solved the mystery of Death Valley's \"sailing stones.\" Researchers discovered that a rare combination of rain, freezing temperatures, and light winds creates thin, floating ice panels that push rocks across the slippery mud of Racetrack Playa. While GPS data confirms this mechanism for most stones, the movement of the largest boulders remains a subject of ongoing study.
