The only way out of a century of stored-up fuel is to put fire back on the land on purpose. The episode traces the slow turn from total suppression: the 1963 Leopold Report, the Park Service's 1968 natural-fire policy, the 1978 end of the 10 a.m. policy and the 1988 Yellowstone fires. It reckons honestly with why good fire is hard, including smoke rules, liability and escapes like Hermits Peak in 2022.
Everyone agrees fire must return but not on how much escape risk is acceptable, how fast to scale up, or how to weigh controlled prescribed-burn smoke against the risk of catastrophic wildfire.
