ALPINE, Utah (AP) — Firefighters battling a wildland blaze 35 miles southeast of Salt Lake City say the immediate danger has passed and all residents have been allowed to return to their homes after an evacuation was ordered in Alpine.

Authorities say about 100 people were evacuated from 25 homes early Sunday after the Water Tower fire broke out the day before on a mountainside in the Uinta National Forest about a mile northeast of Alpine.

The exact cause of the fire remains under investigation but fire officials believe it was started by a group shooting guns in the area.

The Forest Service said Monday it has burned nearly 400 acres and is estimated to be about 25 percent contained. About 100 personnel remain on the fire lines and full containment is expected by Thursday.
