A Martian Dust Devil This Mars Global Surveyor image shows a dust devil as seen from almost directly above. This tower of swirling air and dust casts a long shadow in the afternoon sun. Spotted in 2012, this dust devil is about 100 feet wide and half a mile in height. About a month later, another dust devil was seen reaching a height of 12 miles!
