Learning from wildfire tragedies

Read the reports. Honor the fallen. Learn.

Every safety rule we carry on the fireline was bought with a life. This page collects the official investigation reports from the fires that taught us the hardest lessons, in the order they happened. They are not easy reading, but they are where we learn.

Official US fatality reports, in order

The United States has the longest tradition of official fatality investigation in the wildland fire world. These are the milestone reports, from Blackwater in 1937 to Yarnell Hill in 2013. Each one changed how the next generation fights fire.

Blackwater Fire

Wyoming

Fifteen killed, mostly CCC enrollees. The dry Thunderstorm that brought the fatal wind shift led directly to the concepts of dry cold fronts and fire weather forecasting.
