The Chinooks are warm, dry winds prevalent on the eastern slopes of the Canadian Rockies. The Chinook people called them “snow eater” and in traditional stories the warm air is a blessing. Storm chaser Kyle Brittain describes the formation of Chinook winds. Dr. Werner Becker, University of Calgary, describes recent research about the effect of Chinooks on migraine patients. Blackfoot elder Duane Mistaken Chief, Kainai Nation, tells their story of the wind - Napi, the trickster, rushing down the mountain. Doc concludes with the Siksika tale, The Bear Who Stole the Chinook.
