Fire threatens desert city

PALMDALE, Calif. —A huge wildfire in the high desert wilderness north of Los Angeles jumped an aqueduct Friday, rushing toward hundreds of houses as firefighters also tried to keep flames from damaging power lines that bring electricity to Southern California.

Some 2,000 structures were threatened and 300 homes were evacuated, Gov. Arnold Schwarzenegger said.

Winds apparently carried embers across the wide concrete channel, with flames rapidly spreading to backyard fences at the edge of Palmdale. Plumes of smoke streamed across the city of 139,000 as a predicted afternoon increase in winds finally arrived.

Helicopters dipped buckets into the aqueduct to make rapid water drops. No homes immediately appeared to have been damaged. Numerous fire engines were in the area. A giant Boeing 747 supertanker arrived over Palmdale to join the battle.

Officials euthanize bear in fatal camp attack

BILLINGS, Mont. —Wildlife officials euthanized a grizzly bear Friday after DNA tests confirmed that the sow and her cubs were responsible for a triple mauling that killed a Michigan man and injured two other campers.

Montana Fish, Wildlife and Parks said in a statement that hair, saliva and tissue samples tested at a Laramie, Wyo., lab determined the adult bear was the same one that rampaged through Soda Butte Campground near Yellowstone National Park early Wednesday.

The sow's three cubs will be sent to ZooMontana in Billings, said Chris Servheen, a U.S. Fish and Wildlife Service grizzly bear recovery coordinator.
