The wildfire quickly spreads, consuming the thick, dried-out vegetation and almost everything else in its path. What was once a forest becomes a virtual powder keg of untapped fuel. In a seemingly instantaneous burst, the wildfire overtakes thousands of acres of surrounding land, threatening the homes and lives of many in the vicinity. An average of 5 million acres burns every year in the United States, causing millions of dollars in damage.
Once a fire begins, it can spread at a rate of up to 14.29 miles per hour (23 kph), consuming everything in its path.
