By 11:30 p.m. on July 24 – the day that some Chicoans heard that a fire had started near Upper Park’s Alligator Hole, an area that hadn’t burned in a very long time – the blaze had devoured 6,465 acres.
The next morning, Cal Fire reported that by 6:46 a.m. the scorching-hot fire, driven by south winds, covered 45,550 acres. The fire had moved at a speed so stunning that while most Chico-area residents slept, it had covered on average almost 6,000 acres an hour.
The Park Fire is one of the fastest-moving — perhaps the fastest — of the so-called catastrophic fires that have occurred in Northern California in recent years. But speed isn’t the only characteristic it shares with megafires. Like other explosive wildfires, it doesn’t sleep.
