DUCHESNE, Utah (ABC 4 News) - The Church Camp Fire, which began on Sunday, continued to burn into the southern part of Duchesne County on Wednesday.
Civil authorities believe approximately 12 structures have been destroyed as of Tuesday night, although the types of structures or specific locations where they were lost was not immediately known.
Officials say the fire was estimated to be 4,000 acres as of Tuesday night, but due to smoke and limited visibility that number may change.
State and federal fire authorities, along with local crews have set up structure protection on the east and north flanks of the fire.
The mandatory evacuation ordered Tuesday by Duchesne County authorities remained in effect for the Argyle Canyon Road, east of State Road 191 to Gardner Canyon and 2 miles north and 2 miles south of Argyle Canyon Road.
Officials said that until civil authorities and firefighters can insure the public of safe access to the Argyle Canyon Road, it is requested the public avoid travel in the area, allowing firefighters and equipment to work safely.
Officials said that U.S Highway 191 remained open to the public, but because of smoke and fire activity, they requested travelers using the route to use extreme caution and please not stop.
Utah Fire officials said that hand crews would be constructing line and assisting local fire departments with structure protection in the Argyle Canyon area on Wednesday.
Six helicopters, 16 engines, three hand crews and 150 fire personnel were working the fire on Wednesday, and more were on order, while a temporary flight restriction was in place to prevent potential interference with helicopters working on the fire.
