The following is a news release from the Idaho Falls Fire Department.
IDAHO FALLS – A fast-moving vegetation fire in the Henry Creek area burned approximately 482 acres overnight Tuesday, prompting a large, coordinated response from local, state and federal fire agencies that successfully protected nearby homes and structures.
The Idaho Falls Fire Department was dispatched at approximately 11:45 p.m. Tuesday, July 28, after reports of a vegetation fire burning on a hillside near the Cast Iron cul-de-sac. What began as a small fire quickly intensified, spreading rapidly through dry brush as wind pushed the flames across the hillside and threatened nearby homes.
As conditions changed overnight, the incident expanded under a unified command between the Idaho Falls Fire Department and the Bureau of Land Management. Additional resources from Bonneville County Fire District No. 1, Ucon Fire Department, Swan Valley Fire District and the Henry Creek Range Association joined suppression efforts.

The Idaho Falls Fire Department deployed Battalion Chief 1, Brush 2, Tender 5, Brush 6, Engine 7 and Brush 7. The Bureau of Land Management deployed two bulldozers, five heavy engines, four brush engines and an aircraft. Additional engines, brush trucks, command staff and water tenders from assisting agencies supported firefighting efforts throughout the night.
The Henry’s Creek Rangeland Fire Protection Association also aided in containing the blaze.
No evacuation order was issued, though several residents voluntarily evacuated their homes as firefighters worked to protect nearby structures.
Thanks to unified command, the coordinated efforts of all responding agencies and favorable wind conditions, firefighters successfully prevented the fire from reaching homes and other structures. No homes or structures were lost.
As of Wednesday morning, firefighters remained on scene conducting perimeter patrols and mopping up hot spots to ensure the fire remained contained.
The cause of the fire remains under investigation.
