Notes (Do Not Cite): Listing of 6 factors complicating fire behavior prediction in insect-damaged spruce stands on the Kenai Peninsula. Fire behavior observations from the Pothole Lake fire of May 1991. In early spring prior to greenup a crown fire in mixed live/dead standing spruce could spread at 0.75-1.2 mph in 20 mph winds. Flame lengths would be 100-130 ft. Spotting would run 1/4 mile. Normal summer conditions would be a rate of spread about 0.6-0.9 mph, flame lengths 80-105 ft.
