How high can dunes in the Namib Desert grow?

The sand dunes in the Namib Desert are among the largest in the world. These massive formations can reach heights of up to 1,065 feet (325 meters).1

In some areas of the desert, these accumulations of sand—often referred to as sand mountains—can reach heights of approximately 300 meters (1,000 feet). Many of these structures are star dunes, which are shaped by winds blowing from multiple directions, resulting in a pyramidal form with radiating ridges.21
