On August 20, 1910, serious forest fires in and around Northern Idaho “blew up” into arguably the worst wildfire in U. S. history. More than anything else, weather conspired to set the stage for this catastrophe, starting as winter rolled into spring. April brought record temperatures to the Bitterroot Range along the Idaho-Montana border.
May … June … July … barely any rainfall and unprecedented heat turned the great forests into gigantic tinderboxes. By early August, scores of fires burned in the Coeur d’Alene National Forest and across the border in western Montana. Lacking manpower, despite the recruitment of thousands of new firefighters, the Forest Service asked for, and received, help from the Army.
Depending upon your definition of what constitutes a separate fire, the area still had two to three thousand blazes burning by August 17-19. Yet, after weeks of brutal effort, officials felt they were finally turning the corner.
All that changed on the 20th when an eruption of hurricane-force winds roared in from the west. Within minutes after the blast hit, sparks turned into flames, thickets of smoldering brush became boiling infernos, and burning trees virtually exploded. Crown fires roared up hillsides and over ridges in seconds, it seemed.
Within no more than hours, all those separate fires in northern Idaho and western Montana became one monstrous conflagration – “the Big Burn.” Walls of flame engulfed vast expanses of forest that had hardly been touched before.
Firefighters armed only with hand tools – shovels, axes, hoes, crosscut saws, and perhaps a few buckets – could do little to affect their own fate. Fickle wind shifts killed blocks of men by the dozen, by the score, or horrifically alone. Sometimes men desperately fighting the inevitable won: a providential blast turned the flames aside and spared them. Men threw themselves into the streams; better to drown than be burned alive.
Where there was no fire, ash and black smoke created a surreal landscape and darkened the sky. Reportedly, smoke blocked the sun a hundred miles into Canada, in Denver, and even as far east as New York state.
Finally, after perhaps 36 hours of aptly-named Hell, the wind relented and light rain began to fall. Residents of Wallace could hardly believe their luck; relief came in time to save all but a third of their town. A number of other villages weren’t so fortunate.
By most accounts, 85 people died in the flames: seven “civilians” and 78 firefighters. No one even tried to count the toll levied on the animals living in the forest. Over three million acres of forest burned, an area almost the size of Connecticut. Thousands upon thousands of tree that escaped the flames died from the intense heat and loss of foliage. Loggers salvaged perhaps ten percent as lumber, the rest was slowly cleared and burned.
A full discussion of the Big Burn and its aftermath is beyond the scope of this article. But it has been persuasively argued that the Big Burn saved the U. S. Forest Service. Created just five years before [blog, February 1], many saw the Service as a “useless” expense, with “no practical use.” But now, newspaper were filled with accounts of heroic crews fighting, and sometimes dying, to quell the inferno. Supporters leveraged that publicity to expand the Service and promote its fire-fighting mission.
However, to this day, experts are still debating how to best manage fires in our national forests and other public lands.
