The lightning-caused Cow Hollow Fire in Duchesne County had grown to 60 acres by Saturday morning, according to the Forest Service.

The fire — about 9 miles south of Fruitland on the Duschesne-Roosevelt Ranger District of the Ashley National Forest — was burning in heavy timber in a steep canyon accessible only by foot, said Louis Haynes, public affairs officer for the forest.

Haynes said in a written release that 130 firefighters, three engines and two helicopters have been assigned to fight the blaze. Firefighters were working Saturday to improve access to the fire and cut a fire line, he said.

No structures are threatened by the Cow Hollow Fire, which was reported on Friday afternoon.

Another blaze in Utah sparked by lightening, the Pine Valley Fire in Beaver County, was completely contained on Friday. It had grown to about 110 acres.

Also Friday, crews had fully contained the human-caused Pony Fire, which scorched 929 acres at the base of Mount Simpson in Tooele County.
