A wildfire in a section of the Silver Falls State Park in Silverton Friday has caused the closure of several back-country trails and the evacuation of about 185 people.

The fire was burning fewer than 6 acres in the southeastern corner of the state park, according to the Oregon Department of Forestry. The people evacuated from the area were part of a YMCA youth camp.

Helicopters and air tankers are among the units being used to help put out the blaze. Other areas of the park have remained open while crews work to put out the wildfire.

No injuries have been reported.
