Season 27, Episode 9

This season, Oregon Field Guide assembles its largest, most complex expedition ever to take you on an unparalleled adventure of discovery. We travel deep into the wilderness to explore and bring back the first images of a hidden geologic wonder right here in Oregon.


For 27 years, Oregon Field Guide has been OPB’s weekly TV news magazine exploring the ecological issues, natural wonders and outdoor recreation of the Northwest.

This season, Oregon Field Guide assembles its largest, most complex expedition ever to take you on an unparalleled adventure of discovery.

The Oregon Field Guide team, along with a crew of five canyoneers and adventure photographers travel deep into the wilderness to explore and bring back the first images of a hidden geologic wonder right here in Oregon.  Navigating downstream from a huge glade fed by two 100-foot waterfalls, we traveled over nine major waterfalls, through a dramatic grotto, to end up at the gates of the narrow slot canyon.

The resulting half-hour documentary will air on OPB TV on February 4, 2016, or streaming online.  Join us for Discovering Valhalla: Oregon's Hidden Gorge.

Special thanks to all of our funders, crew and volunteers who made this show possible. Additional production equipment provided courtesy of Pro Photo Supply.
