On August 25, 2026, an unoccupied semi-truck struck an open section of the Enbridge Line 5 pipeline near Saxon in Iron County, northern Wisconsin. The collision caused a massive leak of liquid natural gases, including propane and butane, which created a dense, fog-like cloud. In response, authorities implemented emergency measures such as preemptive evacuations of nearby homes, power outages, and a temporary no-fly zone. Emergency crews were able to isolate the damaged section, and no injuries were reported. The incident occurred near the Bad River Reservation close to Lake Superior.
