The Lost Creek Fire in 2003 burned over 20,000 hectares of forest in Crowsnest, threatening nearby towns. A seasonal wildfire grew dramatically in size and intensity to a 6km wall of flames reaching 50m high, releasing energy equivalent to an atomic explosion every 30 minutes. The fire had both positive and negative impacts on the local economy, environment, and residents - businesses in some sectors suffered losses while others profited, burnt areas saw new plant growth but were initially unsightly, and residents had to evacuate but also found the fire fascinating to watch.
