Water-dropping helicopter battles Williams fire.

LOS ANGELES (CNS) - A new management team was  preparing to take control today of the fire that has burned more than 3,600  acres in the San Gabriel Mountains above Glendora and prompted campground  evacuations forest officials said.

The fire began about 2:15 p.m. Sunday near  East Fork Road at the San Gabriel Canyon, off Highway 39, Angeles National  Forest spokeswoman L'Tanga Watson said.

The blaze, believed to have originated in the  trailer community of Camp Williams, grew from four acres to about 3,600 acres by  8 p.m., Watson said.

The fire was five percent contained, and  darkness prevented an accurate assessment of further fire growth until daylight  when fire officials could fly over and size up the fire's overnight  progress.

``There's no estimate of full containment,''  U.S. Forest Service public information officer Robert Brady said. ``The fire is  moving to the north- northeast toward the (Sheep Mountain) wilderness  area."
