Oregon Field Guide Season 21 Episode 5

Overview:
In Oregon's central Cascades along the Metolius river, timber harvesters and conservation groups are working together to find a better way to maintain the forests and prevent catastrophic forest fires. The process of selectively thinning restores the health of the forest and provides economic benefits to timber harvesters. Volunteer cleaners nit pick the Oregon Caves. But they’re not looking for trash. The hunt is for something much, much smaller. Even lint and hair contaminates and alters the sensitive cave ecosystem. Explore the fascinating history of Portland's hidden and not-so-hidden public stairways.
