Lander, WY – Prescribed burns are designed to reduce the risk of wildfires and protect homes near forests. But a prescribed burn near Lander this weekend got away from Forest Service personnel and has destroyed four structures. Fire Information Officer Pam Wilson says two of those were summer homes and she was still waiting on more information about the other two structures. According to the Associated Press, homeowners are accusing the Forest Service of incompetence saying the agency left the burn unattended. But Wilson says crews were simply caught off guard by a surprising change in weather conditions Monday. Wilson says the burn itself went according to plans, but the front that moved into the area brought winds that were twice what was predicted. Still Wilson says two investigative teams will look into the planning and procedures of the prescribed burn.
