The Active Volcano in Oregon; Mount Jefferson

While many people know of Oregon's tallest active volcano (Mount Hood), few people know of its second tallest volcano. And yet, Mount Jefferson, standing at a towering height of more than 10,000 feet above sea level is one day likely to erupt again. This video will discuss Mount Jefferson, its hazards, and its last eruption which occurred only 1,000 years ago. Thumbnail Photo Credit: "Mt.
