Two more structures have been lost, though it was not immediately clear if those were homes as well. Outbuildings have been impacted as well, according to fire officials.
Six hand crews and 12 fire engines arrived Sunday to help the 20 fire engines, a helicopter, three airplane tankers and two speed planes already attacking the fire, which remained no more than 5 percent contained as it burned through grass, sage and pinyon-juniper. The crews are working on securing the perimeter closest to homes, along with establishing a containment line around the rest of the fire.
Despite that, fire officials have lifted Saturday's evacuations for Taylor Mountain Road. Steinaker State Park remains closed, however, with active fires still southwest of the beach, according to Utah State Parks. A helicopter is using the park for water and refueling. About 150 to 250 campers, boaters and picnickers had been evacuated from the park Saturday.
U.S. Highway 191 is also open again, following Saturday's closure.
"They're still going to restrict travel" to people who just want to look at the smoke, but residents are being allowed back, Birchell said.
The cause of the fire remains undetermined.
While no figures were immediately available for how many structures were in danger, Steinaker State Park rangers reported 20-foot flames were threatening park buildings, including a maintenance building.
