The Wilson Fire, located above the Mogollon Rim 2.5 miles north of Sedona, is 100% contained at 1.8 acres.
Two engines remain on scene and though the fire is fully contained, crews will spend the day looking for and extinguishing hot spots near the containment lines--working toward full control.
A fire is considered "contained" when firefighters are confident the line around the perimenter of a fire will prevent the fire from spreading any further. The line is mostly constructed by firefighters using tools to dig down to unburnable mineral soil and can include other barriers, such as roads.
A fire is considered "controlled" when it has no chance of expanding in any way due to the line being strengthened to the point that flare-ups from within the perimeter of the fire cannot break through the line.
Crews will perform helicopter bucket drops throughout the day to work toward full control and eventually to the point of the fire being completely out.
The fire originated on a flat mesa located within the 2006 Brins Fire burn scar and was reported at 1:30 a.m. on Monday by a pilot flying over the area. It's cause remains under investigation.
