PROMONTORY -- Firefighters have made some progress this morning in fighting a lightning-sparked wildfire in Box Elder County.
Jason Curry, public information officer with the Utah Division of Forestry, said single-engine planes and a helicopter have been used to drop water on the flames. Curry estimated the fire has spread to cover about 3,000 acres.
There have been no injuries or structures damaged by the blaze, which started about 7:30 p.m. Wednesday.
In the early hours, structures near the Fort Ranch were threatened. Crews "black-lined" or burned the area surrounding the buildings to create a buffer between them and the oncoming fire.
Curry described the terrain where the fire is burning as "steep, rocky, rugged and very inaccessible by vehicles."
He said fire officials hope to make as much progress as possible before winds pick up this afternoon.
"High winds would be a problem for us," Curry said.
There is no estimate as to when the fire may be contained, Curry said, adding "it depends on how far we can get" before this afternoon.
One thing that has helped in fighting the fire is the decision some time ago to plant what Curry called "vegetative fire breaks" or plants with a high moisture content.
"The fire really slows down when it hits those plants, and that helps," he said.
Between 30 and 40 personnel are fighting the blaze, many of them local volunteers from Box Elder County community fire departments.
