Mount Hood National Forest officials have closed campgrounds, trails and a road because of a wildfire that's been burning for over three weeks in the Columbia River Gorge.

The Indian Creek fire, which started July 4 near a camp 7 1/2 miles south of the popular Eagle Creek trailhead, is burning in 74 acres and has long closed several trails. Forest officials expanded their closure Thursday to include the Wahtum Lake and Indian Springs campgrounds and the road used to access them.

They've also closed the Chinidere Cutoff Trail and a previously open part of the Tanner Butte Trail. The closures are in place to ensure public and firefighter safety, fire officials said.

The Pacific Crest Trail and Punch Bowl Falls are still open.

Fire managers anticipate fall rains will have to extinguish the blaze, said information officer Mary Huels.

Firefighters can't directly access it because it's burning in steep, rugged terrain. They're using helicopters to drop water on the fire and nearby terrain.

Here's a look at other fires burning around the state:

The state's largest blaze, the

The 4,135-acre

The lightning-caused

Fire officials expected to contain the Hawk fire, which is burning 15 miles northwest of Jordan Valley by the Idaho border, by noon Friday. Wednesday lightning caused the approximately 1,400-acre blaze.

The lightning-caused Crane fire is burning about 600 acres southeast of Lakeview. It started Monday and is 40 percent contained.

The completely uncontained, 150-acre Blanket Creek fire is burning nine miles northeast of Prospect. The fire has prompted road and trail closures, according to fire officials. Its cause is lightning.

The 89-acre

Crater Lake National Park announced Friday that it has banned backcountry campfires and implemented other restrictions. The announcement comes amid a stretch of warmer and drier conditions than usual at the park, officials said. Those conditions have upped the fire danger, according to officials.

Expecting hot dry weather over next 7-10 days. Please take a moment to consider your actions and the potential for wildfire starts. — NWCC (@NWCCInfo) July 28, 2017
