HELENA, Mont. -

Fire managers say they expect to have the state's largest wildfire contained Monday.

The nearly 250,000-acre Ash Creek Fire in southeastern Montana was 90 percent contained Sunday night. Fire officials say high temperatures, lower humidity and gusty winds tested the fire lines on Sunday, but they still expect full containment on Monday, and some fire resources are being moved elsewhere.

Firefighters have been battling its spread through the Northern Cheyenne Indian Reservation and the Custer National Forest since June 25.

The Taylor Creek Fire southeast of Fort Howes is now more than 62,000 acres and is 65 percent contained.

There are about 920 personnel responding to all five fires being managed as the Southeast Montana Complex.
