The Vinegar Fire started approximately 2 miles north of the Cabin Creek Administrative Site (origin at lat/long: 45 10 44 x 114 54 19). Crews have put point protection measures in place as of 7/19. The Cabin Creek Airstrip has been closed to general aviation, NOTAM # I0807-141. The Vinegar Fire is one of three burning in the Frank Church River of No Return Wilderness on the Payette National Forest. The Club, Rush Creek, and Vinegar fires were started by lightning on July 15, 2021. A Type 3 Incident Management Team took over the fires on July 19th and returned them to Forest management the week of August 2.
An infrared overflight mission mapped the fire at 2,462 acres as of August 3rd. A crew swap was completed on 8/2, replacing the Alta IHC squad with 5 firefighters, another swap is planned on 8/5. While the Cabin Creek Airstrip and historic buildings are relatively secure on the northeast side where the burnout was done at the confluence of Cabin Creek and Cow Creek, there is still the possibility that future fire growth could threaten the structures from another direction. Firefighters reported 3/4 to 1 inch of precipitation over the weekend, and scattered thunderstorms could brought isolated precipitation to the area as the week progresses.
