The state's largest wildfire, the 108,132-acre Clay Springs blaze, was all but history as crews moved in Wednesday morning to tweak containment lines and douse hot spots.

Fire information officer John Zapell said the fire, believed to be human-caused but still under investigation, was officially 94 percent contained as of Wednesday morning with full containment projected by Friday.

"We're mostly just mopping up any hot spots and beginning fire-suppression repair work on fences, things like that," he said.

It has not been cheap to subdue the fire, which began June 27 and has burned timber, grass, brush, pinyon and juniper spanning portions of Millard and Juab counties. The price tag? More than $6.5 million as of mid-week, according to Interagency Fire Center estimates.

Meanwhile, lightning sparked new fires in the golden grass in Box Elder County. The Meadow Fire, that began July 10, about 20 miles north of Grouse Creek, began on BLM land, and high winds have spread the fire to more than 1,500 acres, with 10 percent containment, according to BLM spokeswoman Teresa Rigby. Two homes and 10 outbuildings are threatened, but not in immediate danger so no evacuations were made.

On the east side of the Pilot Mountains, near the Nevada border the Rhyolite Fire began Wednesday afternoon and had grown to 1,200 acres on BLM land and was zero percent contained. The cause is under investigation.

Box Elder County dispatchers also said several small grass fires are also burning in the county due to lightning strikes, but none has threatened any homes or structures.

In central Utah's Manti-LaSal National Forest area, the Seeley Fire had burned 47,578 acres and was about 87 percent contained. The blaze, sparked by lightning June 26 about 15 miles northwest of Huntington, was expected to be fully contained Sunday morning.

Several hundred firefighters were working to complete containment lines as the interior of the blaze continued to smolder in timber, sage brush, pinyon and juniper. Evacuation orders had been lifted for the Electric Lake area and Cleveland Campground, but Clear Creek remained under evacuation.

The lightning-sparked Wolf Den Fire, which burned nearly 17,000 acres, was expected to be fully contained as of Aug. 1, said fire information officer Kelsey Birchell. Containment lines had been cut around 85 percent of that fire 40 miles south of Vernal, with Wednesday's focus on the rugged, steep southeastern edge of the blaze.

The Shingle Fire, believed to be human-caused but still under investigation, was fully contained. That blaze, which began July 1, had burned nearly 8,100 acres of timber, grass and pine six miles east of Duck Creek Village.

A small fire was sparked by lightning in Taylor Canyon near Ogden and east of the base of Malan's Peak. The fire burned less than an acre of brush before being contained with multiple helicopter water drops.
