White River Ash
The White River Ash is a 1,200-year-old ash deposit. It was formed by two large (VEI 6) explosive eruptions from the stratovolcano of Mount Churchill that occurred around 850 AD and blanketed 340,000 km2 (130,000 sq mi) of Yukon and Northwest Territories, Canada and the U.S. state of Alaska with ash.[1] Traces of the ash has been identified in Ireland and Northern Europe.
