Larimer County, CO (KMGH) -- After three days, crews are finally getting at least a little foothold on the wildfire raging in northern Colorado.
They're calling the High Park fire 5-percent contained.
Some evacuated residents may be allowed back home soon.
But incident commanders also are preparing for more evacuations.
And the size of the fire -- and the cost of fighting it -- are climbing like the smoke filling the sky.
"Right now our acreage is at 43,433, so a very large fire," says Nick Christensen, Larimer County Sheriff's Office.
"The cost, at the end of our operational period yesterday was 1.6 million dollars," says Bill Hahnenberg, Incident Commander.
70-percent of the High Park fire is burning on private lands. It's about 15 to 20 miles west of Fort Collins, home to Colorado State University.
Federal officials have pitched in resources to help local firefighters.
They say the High Park is just one of 19 large wildfires emergency crews are battling in nine different states.
