Horseshoe Lake near Big Lake, Alaska. A brush fire was started Thursday morning off a 4 wheeler trail. Fortunately it was not very windy and was in an area the community had mitigated for wildfire. The fire crossed the 4 wheeler trail but flames remained on the ground and firefighters were able to get hose around it and put it out fairly quickly. The exact cause is unknown but could have been from debris on a hot 4 wheeler muffler getting into the dry stump, cigarette or match thrown down. Thanks to West Lakes Fire Department and Mat Su Forestry for their response!
