Oklahoma City resident Robert Oglesby shot this dust devil video near Tucumcari, New Mexico last week. In the video you can clearly see the dust devil is taller than the large wind turbines in the foreground.Click here to watch the video. Dust devils, which are sometimes called "dust whirls" or "sand augers," can range in size from only ten feet tall to up several thousand feet tall. Dust devils are usually harmless but on rare occasions they can grow large enough to pose threat to both people and property.Dust devils are very similar in tornadoes in that both are vertically rotating columns of air. Unlike tornadoes, dust devils form under clear skies while tornadoes are associated and connected to the bases of strong thunderstorms.Native American tribes refer to dust devils as "chiindii," or spirits.  If the dust devil spins clockwise it is considered a good spirit. If a dust devil spins counter-clockwise, it is said to be a bad spirit.
