ROCKY MOUNTAIN NATIONAL PARK, Colo. (AP) — Crews are building a fire line on the southwest side of a 2.3-square-mile wildfire in Rocky Mountain National Park.

Park officials said Thursday crews set up pumps to draw water from a creek to help with firefighting.

About 60 people are fighting the Fern Lake Fire.

The fire started Oct. 9. The cause is still under investigation.
