Two different dune fields on Titan: Belet (top left) and Fensal (bottom left), as imaged by Cassini's radar. The image also shows two similar dune fields on Earth in Rub Al Khali, Saudi Arabia.
Fensal is at higher latitude and elevation than Belet and clearly shows thinner dunes with brighter and wider areas in between, suggesting less abundant dune material in this region.
