FORT COLLINS, Colo. (AP) - Crews have fully contained a wildfire in the foothills west of Fort Collins.

Larimer County sheriff's officials said higher humidity and lower winds overnight helped firefighters reach full containment Wednesday.

The 1,348-acre Galena Fire prompted evacuations after it broke out Friday, but residents were allowed back home the next day.

Investigators say they believe the fire was human-caused. They have said it wasn't a campfire, controlled burn or prescribed burn that escaped, but they haven't determined the exact cause.

The fire damaged pedestrian bridges in Lory State Park and left four firefighters with minor injuries, but no buildings have burned.
