Sounds like something from a disaster movie, but this actually happened! Unbelievable!

What started as a control burn of 150 acres at the Rocky Mountain Arsenal in Denver, turned into a fire storm.

A dust devil formed from tumbleweed and ended up getting into the flames, and eventually turned into what looks to be a tornado of fire.

The fire then spread and burned an additional acre of land.

Pretty scaring stuff, almost doesn't look real!
