Prescribed fires are set to prevent more destructive fires in the future.

This prescribed burn of 150 acres in Denver, CO. was started with the best intentions of cleaning up an area when this dust devil formed and drew the prescribed fire into it. They say that it crossed the fire line and burned an additional acre.

How is that these guys didn't see this huge dust devil bearing down on them. It's not like it just popped out of no where, look at all the tumble weeds this terror was hauling.

Being from Minnesota, we call those monsters "TORNADOS".
