Tucked away in a corner of this extraordinary planet there is a place called Racetrack Playa. Large rocks move across the playa leaving behind a trail several hundred yards long. It remains a mystery how these rocks are transported. If I approached the problem analytically (as a geologist that’s what I do) I’d have to realize, the rocks are jagged, sharp and heavy and the surface they move across is flat. What could be the driving force?
Hmm…. maybe wind and some water and the playa gets all slippery and off they go. But, why does one rock have a trail that runs east-west and another has a trail that runs northwest-southeast and they cross! Now the plot thickens, I have to spend the night here and see if I can solve the mystery.
