The original story continues below.
Fire crews battling a wildfire in Jefferson County’s Deer Creek Canyon Park area have the blaze nearly 50% contained. Winds are increasing but no structures have been damaged so far.
More than 300 homes have been evacuated, with residents waiting to hear about when they can return home.
Eric Winger and his daughter K.W. were in good spirits as they checked into the temporary shelter several miles away from the fire. He said when sheriff's deputies knocked on his door last night, they told him he had about an hour to grab what he could and leave.
"We were always warned and it's a high fire danger area. But it's never — you never fully expect it and it's always scary when it does happen," Winger said.
The fire located in the Deer Creek Canyon Park area started about 4:45 p.m. Thursday. It has burned about 20 acres, but authorities report no homes have been lost.
The cause of the fire is under investigation.
