Tallest free-standing sand dunes
The free-standing megadunes in the Badain Jaran Desert in the Inner Mongolia Autonomous Region of northern China have an average height of 330 metres (1,082 feet), but have measured as much as 460–480 metres (1,509–1,574 feet) high – which is taller than New York's Empire State Building. Scientists suggest that geology of the bedrock below the dunes as well as high water content in the sand which means that grains "stick" together are two of the factors that explain their extreme height.
