What is the 10 a.m. rule? Controversial firefighting strategy could be back

The U.S. Forest Service mandated the "10 a.m. rule" in 1933 to control wildland fires, aiming to prevent disasters like the Big Burn of 1910. However, researchers identified the "Wildfire Paradox," suggesting that suppression efforts inevitably lead to future wildfires with higher intensities. Consequently, the Forest Service modified and eventually abandoned this policy in 1978.
