An enormous dust deposit on Mars shows the power of Martian wind in a new image snapped from orbit. 

Standing on the surface of Mars is possibly the largest single dust source on the Red Planet: the Medusae Fossae Formation (MFF). Shaped and sculpted by blowing winds over time, this mound of dust and surface material stretches out over 3,100 miles (5,000 kilometers) and lies nestled between Tharsis and Elysium, the planet’s most prominent volcanic areas.
