White River Ash

From Wikipedia, the free encyclopedia

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 blanketed 340,000 km2 (130,000 sq mi) of Yukon and Northwest Territories, Canada and the U.S. state of Alaska with ash.[1]
