Duane Froese of the University of Alberta in a forest of stumps smothered by the White River Ash around the year 843 AD. Froese is pictured in the Yukon Territory, close to the Alaska border and Natazhat Glacier in an area downwind of the great White River eruptions, which spewed from somewhere near Alaska's Mount Churchill.
