The lightning-started, 558-acre Little Bald Mountain fire has been burning 12 miles southwest of Grantsville since July 31. It is about 80 percent contained today. That blaze could be completely extinguished in the next two weeks, according to Don Carpenter with the Division of Forestry.

Box Elder Canyon, South Willow Canyon, North Willow Canyon and area campgrounds remain closed for public safety and to allow suppression equipment to access the area. Because of extreme fire danger, area officials are also asking the public to be cautious of surroundings as they recreate on public lands.

The blaze has crept as close as 2 miles to nearby homes.

With reports of lightning storms moving into the state, first-response teams backed off from the fire Tuesday night to prepare themselves for other potential fires, and the second-response team plans to turn the firefighting efforts over to a third team tomorrow.

Don Carpenter, a spokesman for the state Division of Forestry, said the 198 personnel - including five 20-person crews, two helicopters, five fire engines and a water tender - are wrapping up the blaze. However, firefighters can not access part of the ground that is peppered with hot spots because it is too steep.

"There is an area that is not safe for firefighters, so we won't put a line down on it," Carpenter said, adding that there are some natural barriers, so crews will instead keep an eye on the area and let the fire burn itself out.

A section of the 240-acre Bridal Veil Falls fire in Provo is likewise completely inaccessible to firefighters and will be allowed to burn itself out, said spokeswoman Loyal Clark with the Forest Service.

That human-caused blaze began July 24 in an abandoned restaurant, but investigators are still looking into exactly how it happened.

A helicopter is dropping a small crew on the mountain today and will continue making water dumps at hard-to-reach areas.

Clark said a quarter-mile perimeter is bordered by rocky cliffs. There is no threat of the fire spreading there, and it also will be allowed to burn itself out. She added that it likely would take heavy rains to douse the remainder of that smoldering area.

A 2.5 mile section of the canyon bottom remains closed as a helicopter picks up water and lifts it up the mountain. Fire crews are prohibiting access to anglers and access to a paved trail that runs along the river. That section will remain closed as long as the chopper is needed.

Meanwhile, Nuns and Vivian parks both remain open.
