How Wildfires Work http://science.howstuffworks.com/natu... "In just seconds, a spark or even the sun's heat alone sets off an inferno. 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." Yosemite Wildfire Grows, Fueling Dangerous Winds http://www.scientificamerican.com/art... "A colossal wildfire raging across the western edge of Yosemite National Park swept further into the park on Sunday and forced the evacuation of some its camps due to heavy smoke, according to a park spokesman." Fire near Yosemite grows to more than 280 square miles http://www.usatoday.com/story/news/na... "Even before evacuation warnings reached her rural mountain community ahead of the massive and growing wildfire just to the east, Stacy Geer packed up her two kids and headed to the safety of an evacuation center."
