A wildfire west of Nogales, Ariz., was nearly contained.

The Juniper Fire began Sunday afternoon about 18 miles west of the border city. It was 80 percent contained by Monday evening.

The 161-acre wildfire, the largest of 15 fires so far this year, is burning in grass and low brush, said Heidi Schewel, spokeswoman for the Coronado National Forest.

Three firefighting crews and four engines were assigned. There were no closures associated with this fire; no structures were threatened. The fire's cause of the fire is still under investigation, but Schewel said it appears to be human-caused.
