Mount Rainier National Park officials reported on Facebook Tuesday afernoon:
Thanks to the North Cascades Smokejumpers, Denny the Inicident Commander from the Mount Baker-Snoqualmie NF, and park and regional staff, the Three Lakes Fire is 100% contained. Park staff will be monitoring the site of the fire for a while. The Laughingwater Creek Trail remains closed, but all other park trails are open. Smoke from the other large fires isn't bad in the park today.
The fire was initially reported last Friday, Sept. 14 though it was believed to have been sparked a week prior on Saturday, Sept. 8 by lightning. Though initially reported at about four to five acres, better mapping capabilities put the size of the fire at 7.5 acres on Monday.
According to the incident log, which hasn't yet been updated Tuesday, the fire was one mile west of Three Lakes at the 5,000 foot level, in close proximity to the historic Three Lakes patrol cabin and the Wenatchee National Forest boundary.
