The Claremont Fire has burned approximately 6,564 acres in the Boise Foothills since igniting on Monday, July 6, and remains at just 23 percent containment as of July 10, according to the National Interagency Fire Center. The fire is burning approximately one mile northeast of Boise in Ada County and has drawn a major firefighting response including multiple air tankers.
Fire Behavior and Spread
The Claremont Fire was discovered on the afternoon of July 6 in grass and brush terrain northeast of Boise. It grew rapidly in the afternoon heat, prompting requests for air tanker support within hours of ignition. By the following morning, the fire had exploded in size under dry, windy conditions, burning through the rugged Foothills terrain. By July 8, the fire had burned 6,509 acres and crews were working to establish containment lines along established ridges and roads.
As of Thursday, July 10, the fire held overnight at approximately 6,530 acres, with firefighters successfully keeping the blaze within containment lines — a positive sign heading into the weekend. Boise County issued evacuation levels but has since lowered portions to Level 1 (Be Ready) as crews demonstrate improved control.
BLM Emergency Closure
The Bureau of Land Management issued an emergency fire closure effective July 6 at 8:00 p.m. covering BLM-managed lands, roads, and trails between Bogus Basin Road, Idaho State Highway 21, and Boise Ridge Road. This closure affects popular recreational trails in the Boise Foothills and will remain in effect until the BLM lifts it. The only exceptions are roads maintained by Ada County.
Hikers, mountain bikers, and other recreational users are reminded that closure violations carry significant penalties and can endanger both the public and firefighters working the perimeter.
Air Resources
Multiple air tankers have been making passes over the fire since early in the incident, dropping retardant along the fire's flanks to slow its advance toward developed areas. Helicopters have also been active in the area for water drops and reconnaissance. The use of aerial resources reflects the fire's proximity to Boise and the need to protect homes and infrastructure in the Foothills.
Outlook
Firefighters face continued challenges from hot and dry conditions over the coming days. Above-normal temperatures, low relative humidity, and the potential for afternoon wind events all pose threats to containment efforts. Incident commanders are prioritizing structure protection and have established contingency lines deeper in the Foothills as a precaution.
Residents near the Boise Foothills should remain aware of evacuation zone status and have go-bags ready. Updates on the Claremont Fire are available through the Idaho Department of Lands and the Ada County emergency management website.
