"The Bare fire’s rapid growth to 800 acres and the deployment of over 200 personnel, coupled with a containment trajectory that spanned 12 days, highlight the significant resource commitment required for large wildfires in remote Wyoming terrain."
The Bare wildfire, located 20 miles northwest of Big Piney in Sublette County, Wyoming, was first discovered on August 4, 2026. The United States Forest Service (USFS) is the jurisdictional agency.
