Dan Dallas had defended these communities before. The little towns on the Karuk tribal land are nestled in a gorge along the Klamath River, amidst a million-acre wilderness of Northern California conifer and hardwood that makes up the Six Rivers National Forest. This time, August 2023, a fusillade of lightning strikes had ignited the web of steep canyons south of the town of Orleans in two dozen places, and as the fires expanded, they merged.

As an incident commander for the U.S. Forest Service, Dallas wasn’t called up until fires got big. On the drive from Colorado, he considered the recent experiences that had begun to trouble him.

“I’d been to multiple places, two, even three, sometimes four times,” he remembered in a recent interview. On each fire, he’d followed the Forest Service playbook. Keep the fire small. Contain it quickly. Box it in by throwing hardware at it, bulldozing the ridgetops, and dropping fire retardant slurry or water from planes and helicopters. Don’t light the fuse on a megafire that could reach the nearest town. But he was starting to realize: Even if you don’t light the fuse, you still have the bomb.
