Mt. Hood's Volcanic Past

Clip: Season 24 Episode 2404 | 8m 20s

Mount Hood erupted for nearly a decade, just a few years before Lewis & Clark came through. The mountain many Portlanders regard as part of the city skyline is actually an active volcano with a more recent history of activity than many people realize.
