Fire that prompted Yosemite closure sparked by vehicle

LOS ANGELES - US Forest Service investigators have determined that a motor vehicle is to blame for sparking the massive, deadly California wildfire that prompted a nearly three-week closure of Yosemite National Park's best known landmarks.
Specifically, the Ferguson fire was ignited on July 13 when superheated pieces of a catalytic converter came into contact with dry, roadside vegetation along Highway 140 in the Sierra National Forest west of the park, the Forest Service said in a press statement.
The vehicle believed to have caused the blaze, which originated around sunset near Savage's Trading Post, has not been identified, but officials are asking anyone with information to contact the Forest Service.
