This video shows the ignition of the Sawmill Fire which burned on Coronado National Forest and other lands in April, 2017. 


An explosive material was shot with a firearm, and sparks landing in surrounding dry grass ignited instantly.


This serves to demonstrate the volatile conditions which can be present across the Forest during any time of the year, and how quickly a wildfire can be ignited from any spark introduced to receptive fuel.
