Firefighters are tackling the first major wildfire of the season on the front range of Colorado.

As of 4 p.m. on Wednesday, the Campbell wildfire has burned about 120 acres of timberland. It is located on private land about 15 miles northeast of the town of Guffey in Park County.

Fire investigators believe the wildfire was started by a lightning strike on Tuesday.

At this time, there are no mandatory evacuation orders for residents. However, the Park County Sheriff's office is urging homeowners to begin packing---just in case an evacuation becomes necessary.

About 60 ground crews are now on the scene. That number is expected to double by Wednesday evening. Slurry bombers and helicopters are also attacking the flames from the air.

Although the fire has grown, cooler temperatures and lower humidity levels have helped the fire crews on Wednesday. However, the wildfire is now considered 10% contained.

As a result of this fire, and because of the increasing wildfire danger, both Park and Teller Counties have now issued BURN BANS. This means no open fires are permitted. However, the bans do not affect U.S. Forest Service lands at this time.

The Park County Sheriff's office asks that resident DO NOT call 9-1-1 for information on the wildfire. Instead, there is a hotline that will be updated periodically with the latest information:

Campbell Wildfire Hotline: 719-836-4151
