Random Sand Fact
In Tajikistan, sand ripples can reveal a catastrophe from the ice age.
Most sand ripples are small. Wind or flowing water moves across loose sand and leaves ridges behind.
In Tajikistan, researchers have found the same kind of pattern on a giant scale.
These giant ripples are interpreted as traces of enormous floods. Their shape remained in the sand, preserving the movement of water that once surged across the landscape.
Sand can do more than move. It can remember.
