Firefighters should achieve full containment of the 130-acre Trumpeter Fire in Point MacKenzie by the end of shift today, according to the Alaska Division of Forestry.
The fire was reported to be 75 percent contained as of Friday morning. The 50 firefighters working on the fire have begun mop-up operations to seek out and extinguish any remaining hot spots in the interior of the fire, which is located near South Trumpeter Drive in Point MacKenzie, about 20 miles southwest of Wasilla.
The 10-acre increase in size from Thursday is the result of more accurate mapping, not fire activity.
Firefighters are working today to continue strengthening containment lines by mopping up 100 feet in from the perimeter of the fire. Firefighters have a hose line around the entire perimeter and will be using water to douse any remaining hot spots that are found.
The biggest danger at this point for firefighters is not the fire itself but fire-weakened trees that pose a risk of falling as firefighters conduct mop-up operations. Hazard trees are being identified and removed by sawyers on crews to mitigate the danger.
The Pioneer Peak Hotshots and Gannett Glacier Crew, both based in Palmer, account for the bulk of the personnel working on the fire and both crews will remain in place through today, barring any other fires that require initial attack.
The human-caused fire started on Wednesday afternoon and is under investigation.
