Park rangers escorted visitors out of Debs Park this afternoon after a small fire brush began at the base of a hill near Hermon. Approximately 80 firefighters assisted by helicopters took about an hour to put out the blaze that was reported shortly after 2 p.m. near 5600 block N. Via Marisol, according to the Los Angeles Fire Department. No injuries were reported. Officials were trying to determined what caused the blaze, which could be seen from the nearby Arroyo Seco Parkway as it burned in the brush below Bushnell Way Elementary.
