In the summer of 1910, hundreds of wildfires raged across the Northern Rockies. By the time it was all over, more than three million acres had burned and at least 78 firefighters were dead. It was the largest fire in American history, and it assured the future of the still-new United States Forest Service.Rocky Mountain PBS has it scheduled at 8 p.m. on February 3.
I have already seen commenters on a wildfire-related site say, hey, that man is using a pulaski too, which postdates the fire and assistant ranger Ed Pulaski's heroic actions. Well, yes, I don't think there was any movie footage in 1910, so the filmmakers probably substituted footage from the 1920s–1940s (the pre-hard hat days).
Bill Gabbert here offers some "behind the scenes" images, including the firefighters trapped in the Pulaski Tunnel, a/k/a the War Eagle Mine.
