👉 The "Montana Fumes" refer to a series of mysterious, toxic gas emissions that have been reported in western Montana, particularly around the town of Missoula and the surrounding areas, especially near the Gallatin Range. These fumes are believed to originate from natural sources, including geothermal activity and the decomposition of organic matter in the region's wetlands and forests. However, the exact cause remains debated, with some scientists suggesting industrial or human-related contributions, such as leaks from underground reservoirs or mining operations. The phenomenon has sparked concern due to potential health risks, including respiratory issues and neurological effects, though definitive evidence linking specific incidents to these fumes is still lacking.
