A Los Angeles City Fire helicopter drops water on flames, Wednesday, June 24, 2015, in Santa Clarita, Calif. About 1,000 people have been evacuated from homes as a 100-acre wildfire burns through brushy canyonlands north of Los Angeles.

Wildfires are charging through several dry Western states, including a blaze in California that showed new life after burning for a week and forced some communities to flee their homes. A look at the latest hotspots and what crews are doing to control them:

SOUTHERN CALIFORNIA

A huge forest fire that has been burning through rugged terrain in the San Bernardino Mountains for more than a week forced evacuations as it stretched northeast into the desert.

The blaze about 90 miles east of Los Angeles showed new life as winds shifted. The tiny Mojave communities of Burns Canyon and Rimrock were ordered to leave their homes Thursday. Evacuations were voluntary in nearby Pioneertown.

A change in wind direction also forced several hundred campers to evacuate Wednesday.

Crews relied on retardant-dropping aircraft to battle the hard-to-reach fire, which began June 17 in mountain wilderness. Officials say they had to temporarily ground air tankers for safety reasons after a hobbyist's drone flew over the fire, but flights resumed Thursday.

It has charred more than 36 square miles of old-growth timber and brush and was partially contained.

Meanwhile, a wildfire north of Los Angeles that drove about 1,000 people from their homes and briefly shut down part of a major freeway was reduced to mostly embers.

People could return about nine hours after the blaze broke out Wednesday in Santa Clarita. At its height, some 500 homes had to be evacuated as flames moved close. Damage was limited to one garage.

NORTHERN CALIFORNIA

A wildfire has grown to more than 26 square miles in inaccessible terrain south of Lake Tahoe and has led to some voluntary evacuations Thursday, officials said.

No buildings have been damaged, but the small mountain town of Markleeville is under a voluntary evacuation warning, according to the Bureau of Land Management. Several campgrounds were evacuated earlier in the week, and two highways have been closed.

About 900 firefighters are battling the blaze ignited by lightning Friday about 20 miles west of the Nevada border. The fire is partially contained.

Meanwhile, crews have contained a 533-acre fire about 50 miles east of San Francisco near Antioch that had led some 30 homes to be evacuated Wednesday night, news station KNTV reported. No structures were damaged.

ALASKA

Wildfires have shown significant growth, but fire managers say there have been no new evacuations from threatened communities.

Nearly 300 fires were burning across almost 945 square miles in Alaska, with much of the activity in the dry and hot interior. Fire managers are prioritizing where to send fire crews stretched thin as older fires winds down.

Earlier this week, many residents from one threatened interior village, Nulato, fled by boats to other villages.

In another village, a tribal nonprofit organization flew out more than 60 elders, children and vulnerable adults from Tanana. Victor Joseph, president of the Tanana Chiefs Conference, says smoky conditions have prevented more evacuations from the village.

OREGON

A wildfire scorching a remote part of southwestern Oregon has grown to more than 8 square miles, but hundreds of firefighters have worked to get it more than halfway contained.

Incident commander Doug Johnson said heat, lower humidity, gusty winds and possible thunderstorms are expected this week, which will test the containment lines. He says firefighters will remain vigilant.

The lightning-sparked blaze started June 11 and is burning in the Rogue-River Siskiyou National Forest.
