Why do the Smoking Hills smoke?
In the Smoking Hills area of the Canadian Arctic coast active areas of fire-baked rock or "bocannes" occur in Cretaceous mudstones along sea cliffs and in areas of recent slumping. Extinct and active bocannes are marked by bleaching, baking, and reddening of otherwise dark mudstones. Activ...
