The Pakwash Lake forest camp in Northwest Ontario, Canada sustained a significant straight line wind derecho event on the morning of July 18, 1991. The winds were captured in full detail by a Boise Cascade logging camp worker and were later condensed into this training video by Boise Cascade Canada.

Winds caused substantial losses for Boise Cascade along with a substantial wildfire hazard in the years that followed. The damage ranged for 70km in length, 25km wide. Winds were over 95km per hour. Combined into this video is a regional news report, interviews with logging camp workers and additional damage survey video recorded by Boise Cascade.
