Newberry Volcano is the largest Pleistocene volcano in Oregon covering an area of more than 600 square miles with a volume of more than 100 cubic miles. The volcano probably began forming about a 500,000 years ago and the first caldera formed about 300,000 years ago. Over the next 200,000 years the volcano continued to erupt, filled the caldera, and rebuilt a summit cone. About 80,000 years ago another series of large eruptions resulted in a second summit collapse which again formed a caldera. The caldera was about 1600 feet deeper than the present caldera and over the next 80,000 years, continuing eruptions have filled the caldera to its present depth. Over the last 12,000 years there have been 6 periods of eruptive activity in the caldera, with the last one ending only 1,300 years ago.
