#TrinityRidge #IDFire Afternoon Update ^NH

Current Situation:

Firefighting efforts on the Trinity Ridge Fire will be consolidated under the Alaska Type 1 Incident Management Team lead by Incident Commander Tom Kurth.

The Boise National Forest has reduced the size of the closure area around the fire. The revised area closure 0402-00-0024 (Revision #6) dated September 5, 2012. Details and a map of the current closure are available on Inciweb:http://inciweb.org/incident/map/3088/2/

Northern Portion of the Fire Area:

Firefighters continue to build contingency lines on the northern portion of the fire. Suppression repair continues along the western edge, following the suppression repair plan.

The Alaska Type 1 Incident Management Team will hold a community meeting in Idaho City at the Basin Elementary School on Friday, September 7 at 5:00 p.m. This is an opportunity for the public to meet fire management officials from the Alaska team and receive current updates on the fire situation.

Southern Portion of the Fire Area:

Progress continues as more fireline is declared contained and the fire operation moves towards patrol and monitor status. This has led to a modification of the area closure and the opening of the Pine-Featherville road, as well as the road to Baumgartner campgroud, to all traffic beginning at 7 a.m. today.

The corridor from Pine to Featherville and up Cayuse Creek will now be in patrol status from the road. Air resources will be monitoring areas of the fire, as some uncontrolled line exists in the Boiler Grade Creek area along Road 126. To the south and west, crews will need one more day of mop-up in the Green Creek basin before turning the area from Trinity Lakes down to the South Fork Boise River over to patrol status by aircraft. Fire crews continue rehabilitation efforts on dozer and hand lines, as well as slash chipping, road grading and snag falling.

Beth Lund, Incident Commander for Great Basin Team #1, wants to thank all those that have made this effort a success. She would like to specifically thank the Sheriff’s Department, Idaho National Guard, and the local residents for their patience and support.
