Oregon Field Guide Explores Unusual Caves, Airs Aug. 16, 2009


Join OREGON FIELD GUIDE for an exclusive visit to a unique series of caves that only a few people have ever seen. Located on private land, this maze of passageways and grottos is home to a variety of wildlife. Tune in to the stations of Oregon Public Broadcasting on Thursday, August 13 at 8:30pm and Sunday August 16 at 2:30am & 6:30pm, to find out how the owner is trying to protect it.

Talus Caves - Thousands of years ago a massive avalanche of rocks — some as small as a ball; others as big as a house — settled into a formation honeycombed with grottos and passageways. No one knows exactly how large the area of fractured rock extends, but it clearly covers many acres. FIELD GUIDE joins a group of explorers to squeeze between rocks and chimney up slots exploring the complex maze. It’s a disorienting journey through a unique natural area that the owner wants to assure remains unique and natural. Learn how an alliance with the Three Rivers Conservancy will help keep it that way.

Adventure Photographer - Meet an Oregon photographer who is just as extreme as the athletes he photographs. He captures athletes in extreme conditions as only another athlete can. His story is not only about the physical challenges of dangling from cliffs or withstanding uncomfortable conditions. At 29, he faced cancer, and using the same determination he brings to his profession, beat it.

Global Warming - Willamette Valley vineyards are finding that global climate change is upsetting the balance of their grapes and is as real a threat to their crops as disease or pests. One grower notes that when he began his vineyard in 1979, 550 feet was the maximum elevation he could plant vines. Now, he can plant up to 700 feet. Others note that records show harvest dates are two to three weeks earlier than a century ago. Warmer temperatures mean higher sugar and alcohol content for their fruit, requiring more intervention by the wine maker to produce a palatable product. From Newberg to Nappa, the industry is feeling the effects, making it imperative for growers to try and match what they plant now to the climate of the future. Cool climate varietals like the pinot noirs popular flourishing today, may have to give way to grapes that are more heat tolerant.
