Musselshell County has lifted an evacuation order for about 50 homes southeast of Roundup threatened by a 5½-square mile wildfire.

Jolene Sealey with Musselshell County Disaster and Emergency Services said the evacuation was lifted Monday after crews reported that the Wilson Fire was 60 percent contained.

U.S. Highway 87 south of Roundup has been re-opened to traffic, but a 35-mile-per-hour speed limit remains in place in the fire area.

The human-caused blaze ignited Saturday and quickly grew as it burned through tinder-dry timber and sage brush.

Sealey says some outbuildings but no houses have burned.

The fire remains under investigation.

Fire officials hope to have the blaze fully under control by Tuesday.
