From the text ... 'Lessons learned: Deeply shocked by the Mann Gulch tragedy and subsequent firefighter fatalies in California, the Forest Service initiated reforms to prevent future disasters. Thanks to improved training, equipment, and safety techniques, another tragedy was averted on August 29, 1985, during the Butte Fire on the Salmon National Forest, ID. Seventy-three firefighters were entrapped for up to 2 hours by a severe crown fire. By calmly moving to preestablished safety zones and deploying their fire shelters, all 73 firefighters escaped serious injury. In part, they owe their lives to the lessons learned from the Mann Gulch Fire.'
