There were several slurry drops on the blaze, said Marya Washburn, spokesperson for Boulder-Fire Rescue.

No structures had been damaged or destroyed Saturday night.

The fire ignited in an open space adjacent to the National Center for Atmospheric Research around 2 p.m, Washburn said. It was zero percent contained Saturday night.

At least 50 firefighters batted the blaze amid wind speeds of up to 25 mph, according to BOEM.

“We are thankful for the swift action and response to this wildfire by our firefighters and first responders,” said Gov. Jared Polis in a statement. “State officials have spoken with Sheriff (Joe) Pelle this afternoon and the state has deployed two firefighting aircraft, including a single-engineer tanker and type 2 helicopter, and stands ready to assist with the response. We will continue to monitor this evolving situation.”

As a result of the blaze, Eldorado Canyon State Park was closed when the park was at full capacity and the county activated an emergency operations center.

During a 7 p.m. update, Washburn said that residents should be prepared to see and smell more smoke during the evening because of changes in atmospheric conditions but the this did not mean the fire was growing or getting nearer.
