Overview
- Fire managers report the Bonneville Fire’s perimeter is about 95% contained while heat, smoke and active hotspots persist inside the burn scar.
- Overnight infrared flights mapped remaining hot spots and found only one significant heat area on the perimeter, guiding targeted ground and air suppression.
- Firefighting teams continue mop-up and monitoring and say it may take another day or two to finalize containment and extinguish interior flames.
- Officials identified the blaze as human-caused and have urged the public to avoid closed trails after crews encountered multiple people inside the burn area, a move that forced firefighters to stop operations to address safety.
- City Creek Trail has reopened but other trails and closures remain in place as the University of Utah and local leaders coordinate with crews to protect the hospital, nearby neighborhoods and support services.
