The 13 Active Volcanoes in Oregon

This video discusses each of the 13 active volcanoes in the state of Oregon in detail. Mount Hood, the Newberry volcano, Crater Lake, Mount Jefferson, and a series of lesser-known volcanoes are discussed in detail. The last volcanic eruption to occur in the state was in 1866 at Mount Hood.
