The fire was first reported just after 11 a.m. Wednesday by a mountain biker, and is burning through trees killed by beetles, and grasslands.
One of America's most well-known ski towns is being threatened by a growing wildfire in Colorado's Rocky Mountains. The base of the resort, which includes hotels, restaurants and businesses, was not evacuated.
However, evacuation orders are expected to remain in place until midday on Thursday.
There are a host of crews already working the fire and almost 130 personnel, including eight smoke jumpers, a 20-person hotshot crew, two 20-person Type II hand crews, two helicopters being used to drop water, and multiple local fire agencies.
"We would like to take credit for that but we would like give credit to the wind because when the wind did shift it actually pushed the fire back into the burned area and actually slowed it down", says one firefighter.
Wildfires are still burning in the western United States.
He added that 100 animals had also been sheltered.
A fire authority said at Thursday's news conference that there would be at least 10 engines at the site of the fire by Thursday afternoon. "Wildfire is a natural disaster that happens with regularity". The wildfire started Friday, and its cause remains under investigation.
