September 26, 2020, 9:00 AM: Firefighters held their own against red flag conditions. Crews are now fully suppressing spot fires from the previous days' wind events.
Suppression repair work is now a major component of the firefighting effort. As fire management objectives continue to be met, crews working with hand tools and heavy machinery will repair damages and minimize potential soil erosion and other impacts resulting from fire suppression activities along dozer lines, handlines, roads, trails, staging areas, safety zones, and drop points used during fire suppression efforts.
The East Fork Fire started on August 21, 2020, after a lightning storm passed through the area. The area has not experienced a large fire in about 50 years, numerous standing dead trees create hazards for wildland firefighters. Suppression efforts are focused on protecting critical infrastructure, private property, and other assets near the fire.
Closures are in effect for the Ashley National Forest and Uintah and Ouray Tribal lands. Click on the closure and map tabs for details.
