If you’re wondering where all the smoke came from yesterday you can blame a wildfire near Mountain Home.  Winds fueled a grass fire near Mountain Home Air Force Base just before noon yesterday that blackened around 500 acres and sent smoke into the Magic Valley area. Some homes near the base were evacuated for a time.  The Hog Fire, as it has been named, burned around houses near Airbase Road and Old Grandview Road. No homes were destroyed, but a few outbuilding were lost in the fire.  Investigators believe the fire is human-caused, but they have not determined what sparked the fire.  Highway 51 near the fire was closed briefly, but reopened around 2:30 p.m.   The BLM put a lot of resources on the fire to get it contained.   Officials say wind gusts up to 25 miles per hour moved the flames to the southeast. Crews have managed to knock down the fire and get a line around it. They are now doing mop up work.  The BLM expects to have the fire until control by this evening.
