The Racetrack
The Racetrack in Deathy Valley is not a spot where people race cars. These rocks appear all over Death Valley with track marks trailing behind them. It may look like they are moving on their own, but Death Valley actually gets super cold at night and the ground ices over which causes the rocks to move.
Plain of Jars
There are nearly 2,000 large stones scattered across a plateau in Laos. Some of them are over 10 feet tall! They all have holes in the middle making them resemble jars. Archaeologists estimate that the jars are around 2,000 years old.
