HELENA – The Wilson fire burning north of Wolf Creek has grown to about 500 acres, according to the Lewis and Clark County dispatch center.

Aircraft have been ordered in to help fight the fire including at least one helicopter and heavy air tanker.

No evacuations have been ordered nor are any structures threatened at this time.

On scene are fire resources from DNRC, Wolf Creek, Lincoln, Augusta, Dearborn and deputies from the Lewis and Clark County Sheriff's Office.

The fire was reported as about 5 acres as of 1:30 p.m. Tuesday. 

A telephone line fell across Highway 200 in the area of its junction with Highway 434. Responders were initially concerned it was a power line and planned on closing the road to traffic, but no closure will be necessary, Dutton said.
