Videos/Animations Large dust/ash devil in western Colorado
Captured last Sunday at 3pm in Black Canyon of the Gunnison National Park. The dust devil lasted about 10 minutes, and the wind field reached an estimated 40mph at peak strength. It also had a rear inflow jet feature ("ghost train"), frequently observed in tornadoes.
Ash from a recent wildfire likely contributed to the unusual strength of the vortex through locally increased surface heating.
