SALT LAKE CITY — Firefighters made progress today against the controlled burn that got out of hand in the Cascade Springs area of the Uinta National Forest, and officials lifted a health advisory that had been in place because of heavy smoke from the blaze.
More than 5,700 acres have burned but forest officials say 10 percent of the fire is contained.
About 230 firefighters were battling the fire, with help from six helicopters, 13 engines and two bulldozers.
Today, the Utah Department of Environmental Quality lifted the health advisory issued Wednesday and Thursday after smoke blanketed the valley over Salt Lake and Utah counties.
"The data indicate that air quality is in the 'moderate' range," said Cheryl Heying, Air Quality Planning Branch Manager.
Exposure to the hazy air still should be limited, Heying said.
The fire started Tuesday as a prescribed burn that was supposed to burn 600 acres of mountain brush. But winds blew the embers outside the fire lines.
Roads leading to the Cascade Springs area remain closed, but no structures were being threatened.
An internal review panel from the U.S. Forest Service regional office in Ogden will start reviewing documents leading up to the prescribed burn and look at what went wrong.
"It may not be for a week or two that this gets done because suppression right now is the top priority," said Kathy Jo Pollock, Forest Service spokeswoman.
