CHADRON, Neb. (AP) — A wildfire that’s consuming trees and blackening grassland in the northwest corner of Nebraska has grown to about 300 acres.

Steve Lenzo is deputy forest supervisor for the Nebraska National Forests and Grasslands. He said Tuesday that what’s being called the East Ash Creek fire is on federal recreation area land south of U.S. Highway 20 between Chadron and Crawford.

Lenzo says the fire has grown over the past 24 hours but estimates it’s about 25 percent contained.

He’s optimistic that the 120 or so people on the fire lines Tuesday will make progress in their battle against the flames. They will be aided by four helicopters dropping water from giant buckets.

Lenzo says there have been no injuries and no reports of any structures being damaged.
