Preview Season 27, Episode 7: Gravity Sports

The world cup Maryhill Festival of Speed is the largest gravity sports event in North America where downhill skateboarders and street lugers battle it out in downhill racing. It takes place each year in a place most people have never heard of: historic Maryhill Loops Road in Goldendale, Washington.

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.

Join us this week on Oregon Field Guide for an encore presentation! A geologic mystery in the Cascades captivates tourists heading over Santiam Pass. Lost Lake has two holes, acting like bathtub drains but where does the water go?

Join us also for the Maryhill's "Festival of Speed", a gravity sports festival attracting racers from around the world, and Tenkara, an ancient simple form of fly-fishing from Japan.
