YELLOWSTONE NATIONAL PARK, Wyo. (AP) -- Authorities continue to monitor a large wildfire in Yellowstone National Park.
The fire is burning on about 5,510 acres, approximately 9 square miles.
Fire spokeswoman Marianne Baumberger said Wednesday that fire managers don't expect the fire to spread much through Friday because of cooler weather. Some pockets will continue to burn and produce smoke.
The fire, which is 20 percent contained, is the largest of 11 fires to burn in the park this year. It was started by lightning Sept. 14 and flared up later in the month because of unseasonably warm weather.
All park entrances and roads remain open.
