The Great Fire of 1910, also known as the Big Burn, was one of the largest wildfires in U.S. history. It occurred in August 1910, primarily affecting the states of Idaho and Montana. The fire consumed approximately 3 million acres of forest land, fueled by dry conditions and strong winds. The blaze led to significant changes in forest management and firefighting policies. In response to the devastation, the U.S. Forest Service, led by figures like Gifford Pinchot, began to emphasize fire prevention and suppression strategies to protect natural resources and communities from future wildfires.
