RIMROCK, Wash. (AP) - About 110 firefighters have stopped a wildfire that charred about 175 acres south of U.S. Highway 12 on the east slope of the Cascade Mountains, as well as smaller blazes near Gleed and Wapato.

The Trout fire, the biggest, started Tuesday evening east of Rimrock Lake and roared through grass, brush and timber in steep terrain on state and federal land about 40 miles west of Yakima. Two helicopters dropped water on the fire Wednesday.

The cause of the fire was under investigation. No injuries were reported.

No evacuations were ordered, although residents who live in the Rimrock Lake Retreat were obviously concerned, said U.S. Forest Service spokeswoman Bette Cooney of the Naches Ranger District.

Several dozen cabins and permanent residences sit along the Tieton River, but the fire burned uphill, south of the river and away from any structures, Cooney said.

Firefighters cleared fire lines east and west of the burn and containment was declared late Wednesday, but officials remained concerned about the danger posed by fireworks with the approach of the Fourth of July.

“We did have a wet season and an early (rain) season, which prompted voracious growth with some of our grasses,” said Doug Jenkins, a Wenatchee National Forest spokesman in Naches. “We're really concerned about it.”

Nearly three dozen firefighters from nine agencies battled a stubborn 112-acre brush fire that started at 9:40 a.m. about half a mile north of U.S. 12 northwest of Yakima and advanced within 100 feet of several homes near Gleed early Wednesday afternoon.

The fire was nearly out at about noon but reignited before being brought under control again, Gleed Fire Chief James Kohl said.

“We've had an extended period of hot weather here, and things have kind of cured, dried out a little bit,” Kohl said. “It's a real hazardous year.”

A brush fire blamed on arson blackened about 45 acres near Wapato before being extinguished early Wednesday morning by 42 firefighters, officials said.

“We've eliminated all accidental causes,” Yakima County Fire District 5 Deputy Chief Kevin Frazier said Wednesday.

Flames started accidentally by fireworks can spread just as fast as with arson, District 5 Chief Brian Vogel said. “It's no different than taking a road flare and putting it in the weeds,” Vogel said.
