From The High Country News [September 21, 2021] (Jonathan Thompson):
Late on the hot and sunny morning of July 13, 2021, a distribution troubleman for Pacific Gas & Electric drove up the Feather River Canyon in Northern California to check out a possibly blown fuse on one of the utility’s lines. His route took him past the blackened skeletons of trees burned by the Camp Fire in 2018. Sparked by PG&E’s equipment, it raged through the town of Paradise, killing at least 86 people.
The troubleman — delayed by roadwork — reached the location of the tripped fuse, near the Cresta Dam, at 4:40 p.m. Sure enough, two of the three fuses on the Buck Line had been tripped. As his truck’s cherry-picker bucket lifted him up to the fuses, he suddenly noticed a fire, estimated at about 600 square feet in size. There was a Douglas fir leaning against the line nearby.
He shut off the third fuse, killing power to the system, then descended to the ground to call dispatch, emptying first one, then another extinguisher on the flames, to no avail. Shortly thereafter Cal Fire aircraft arrived, followed by a ground crew. But the grass, shrubs and trees were simply too dry — baked by the kiln-like combination of drought and hot temperatures — and the flames swiftly got away from them, crawling and then exploding up the canyon’s slopes.
By the next day, the 600-square-foot blaze had grown to 600 acres and was spreading north and east at a rate of thousands of acres per day. It joined up with the 2,000-acre Fly Fire — which may have been started by a white fir toppling onto PG&E electrical equipment — and leveled the town of Greenville, forcing the evacuation of tens of thousands of residents. The pyrocumulonimbus plume it spawned rose thousands of feet into the air and sent smoke wafting across the West, affecting the air quality of communities as far away as Colorado. More than six weeks after it started, in early September, the Dixie Fire was still raging, having burned more than 800,000 acres of forest and hundreds of structures. And it was just one of a dozen or so blazes tearing across the state and the region.
PG&E’s equipment, with some help from that errant Douglas fir, may have provided the spark that ignited California’s second-largest fire on record — the exact cause is still under investigation — but climate change clearly fueled it and numerous other recent megafires, from last year’s record-breaking conflagrations in Colorado, to this summer’s destructive blazes in Montana and Oregon. The entire West has been heating up significantly over the past century, exacerbating the effects of two decades of drought and priming dry forests to burn more intensely than ever before.
