A rapidly expanding vegetation fire near Mountain Cove Road in the Boise foothills has grown to approximately 2,000 acres as of Sunday evening, with crews from Boise Fire Department working through the night to contain the blaze. The Claremont Fire, which began around midday on July 6, prompted multiple road closures and trail system shutdowns across Ada County and surrounding areas as firefighting efforts intensified throughout the afternoon and evening.
Fire Growth and Initial Response
The fire began with an initial estimate of roughly 100 acres and expanded rapidly as conditions allowed it to spread uphill and toward the north and northeast. By 3:54 p.m., the fire had grown to between 300 and 500 acres. Within an hour, the size jumped significantly to 1,500 acres, and by 5:18 p.m., crews reported the fire had reached approximately 2,000 acres. No injuries have been reported.
Boise Fire Department deployed additional engines and requested air support, which was brought to the scene. Fire resources remained active throughout the night as crews worked to establish containment lines and protect threatened structures in the immediate vicinity of the fire’s origin.
Road and Trail Closures Affecting Boise-Area Residents
Multiple transportation and recreation corridors were closed to the public as a precaution. Rocky Canyon Road and Shaw Mountain Road were shut down, as was Boise Ridge Road. The Hulls Gulch trail system, a popular recreation area for Boise residents, was also closed at the request of Boise Fire Department.
The Bureau of Land Management issued a temporary closure of all BLM-managed public lands and trails near the fire zone. This closure is scheduled to remain in effect through July 11, 2026 at 11:59 p.m. The BLM closure does not extend to Ada County lands in the area.
Evacuation Status and Public Safety Precautions
As of the 3:54 p.m. update on July 6, no active evacuations were underway. The Boise County Sheriff’s Office indicated that no immediate evacuation orders were in place but stated that circumstances could change depending on fire behavior and resource availability. Structures that were initially threatened by the fire’s advance had their threat status downgraded by the 5:18 p.m. update.
The cause of the Claremont Fire remains under investigation, and officials have not provided an estimated timeline for full containment.
Ongoing Firefighting Efforts
Boise Fire Department maintained continuous operations throughout the evening, with crews positioned to protect structures and prevent further spread into unburned areas. The rapid size increase during afternoon hours underscored the challenging fire conditions typical of early July in the Treasure Valley foothills.
Residents in the greater Boise area who use recreation areas in the northern foothills should be aware of closures and avoid the fire zone. Smoke from the fire may affect air quality in Boise and surrounding communities depending on wind patterns.
What Comes Next
Boise Fire Department will continue to provide updates on containment progress and any changes to evacuation status or road closures. Residents should monitor local emergency management channels and the Boise Fire Department’s official communications for the latest information. The Hulls Gulch trail system and affected roads remain closed until further notice. Updates on fire containment and the removal of temporary closures will be announced as conditions permit.
This incident follows an exceptionally busy period for Treasure Valley fire departments during the Fourth of July holiday weekend. Residents are reminded to report any unattended fires or suspicious activity in forested and vegetated areas immediately to emergency services.
