The tallest dunes, which are pyramidal or star-shaped, are called rhourds and may occasionally reach a height of 1,640 ft (500 m), though dunes in dune massifs are usually 492-820 ft (150-250 m) tall.
The largest sand structures (rhourds, linear dunes or seifs, elbs, and silks) are stable, while barchan dunes may move dozens of meters a year (even hundreds of meters in the sand tongues of Patagonia).
