The Porcupine Fire, discovered July 24, has spread to 3. 5 acres as of September 4, 2026. Firefighters constructed handlines but could not anchor at the fire's base due to steep terrain and cliff locations, leading to further spread during a wind event.

The fire remains confined to limit threats to a communication site, recreation infrastructure, and nearby communities. Firefighting operations use Porcupine Lake Trail #642 for access, with Lake Pend Oreille and Porcupine Lake serving as dip sites for aircraft.
