Oregon Field Guide - Season 23 Episode 11 Balloon Archaeology, Biscuit Fire 10 Years Later, Collier Glacier
10.00 48 minutes Balloon Archaeology
Archaeologists trade working on hands and knees for a viewpoint floating high overhead. Rare access to a helium balloon and remote controlled camera provides the clearest view of the most intriguing discovery in Oregon in years: stone circles that resemble the medicine wheels found in Wyoming and farther east.
Biscuit Fire 10 Years Later
Bernard Bormann, with the Pacific Northwest Research station, had been studying the forests’ of the Siskiyou mountains for years. When the 500,000 acre Biscuit fire burned through his research plots, he first thought all was lost. But in the 10 years since the fire, he’s been able to compare life before and after fire to reveal an amazing amount of new information about how life returns to the forest after fire.
Collier Glacier
For more than a century, photographers have been taking pictures of the Three Sisters’ Collier Glacier. What they didn’t know was they were also documenting the dramatic retreat of Oregon’s largest glacier. USGS Geologist Jim O’Connor takes us to this beautiful area to take this year’s photo and learn what it all means from PSU glaciologist Andrew Fountain.
