More resources are being poured into fighting several fires in south-central Montana, including one south of Lame Deer near Birney.
Rosebud County Commissioner Ed Joiner says that a fire sparked on Friday afternoon due to lightning and has since grown to more than 11,000 acres.
Currently it is burning on state, federal, tribal, county, and private land.
No evacuations have been ordered, and there have been no reported injuries.
One structure was threatened, but crews were able to protect it.
"All is not looking bad right now, a lot of it depends on the wind and weather tonight," Joiner said.
A containment estimate was not available. Fire officials are expected to hold a briefing Monday morning where more information will likely be available.
Joiner said currently there are six fires burning on the Northern Cheyenne Reservation.
Control of fighting the fire was turned over to a Type II team, according to Joiner.
