In the America's with David Yetman
Oregon: Violent Past and Verdant Present
Season 6
Episode 608
More than any other of the contiguous United States, Oregon has been shaped by volcanoes. East and west of the Cascade Range are two different landscapes. On the east side, David climbs through lavas of volcanic glass and follows a mountain bike trail at the edge of a flow, then ventures west to the fertile valleys and the wild Pacific coast in all its glory.
