The Big Rock Fire in Eastern Idaho has grown to 2,500 acres as of Sunday, August 2, 2026, with zero containment reported.
The fire has breached containment lines in the Cress Creek area and is now threatening new areas in Madison County, including the Kelly Canyon Resort.

Impact & Risks

The fire poses significant risks to residents, homes, and infrastructure in the affected areas. More than 30 homes are under immediate threat, and evacuation orders have been issued for several communities, including Heise and areas north of the Snake River. Recreational areas such as campgrounds and BLM-managed lands in the South Fork Canyon corridor have been closed. The combination of high temperatures, low humidity, and strong winds increases the likelihood of rapid fire spread, making conditions dangerous for firefighters and residents alike.
