A wildfire sparked near Chautauqua Park in southwest Boulder Saturday, the fifth new Denver-area fire to spark in five days.

The fire, which officials estimated to be up to five acres before dropping that estimate to 1.5 acres after aerial mapping, sparked around noon Saturday, Boulder Fire Rescue said on social media.

Officials issued an evacuation warning just before 1:30 p.m. for the Chautauqua Cottages, a residential area south of Baseline Road, due to the fire, the department said.

Over 100 firefighters have responded to the scene and air support, including helicopters, have been helping crews work to contain the fire, the department said. While the fire is moving moderately fast, it is doing so away from Boulder.

The fire is the fifth new Denver-area wildfire in as many days as the Front Range has seen several Red Flag warnings due to dry and windy conditions. Only one of the fires, Wednesday’s in Thornton, has directly impacted any structures thus far.
