On this day in 1950, millions of Americans and Canadians experienced something close to a scheduled apocalypse: midday darkness. Smoke from the Chinchaga fire — an immense blaze sprawling across northern Alberta and British Columbia — had ridden the upper winds east, and on September 24 and 25 it blotted out the sun over the US Northeast and Ontario. Streetlights burned at noon. Chickens reportedly went to roost. Ballgames stopped for darkness.
The scale behind the gloom was historic: the Chinchaga fire burned roughly four million acres, the largest single recorded wildfire in North American history. Because the smoke traveled at high altitude, the strangest part was the disconnection — no smell of burning, no ash, just a sourceless dusk that newspapers, tracking it day by day, dubbed the Great Smoke Pall.
In 1950, five years into the atomic age, many frightened residents drew the obvious conclusion and feared a nuclear attack; switchboards lit up across the affected cities. The smoke moved on across the Atlantic — and what it did to European skies the next day became its own strange story, which this series tells tomorrow.
