The 20th-anniversary special re-visits Oregon Field Guide's most memorable adventures, locations and people. It goes behind-the-scenes to see the funny and sometimes frightening things the crew endured to get the story. From an angry peregrine falcon dive-bombing our videographer as he clings to a narrow beam hundreds of feet above the Willamette River, to a runaway horse nearly dragging a reporter over a steep mountain trail.

See what it took for the men of the Lewis and Clark Expedition just to put a little salt on the table. In the winter of 1806, Lewis and Clark needed salt to preserve meat for their return trip. Their men had to boil seawater over a campfire in order to obtain their salt. Scientists such as Dr. Steve Hammond and Dr. Bill Chadwick of the National Oceanic and Atmospheric Administration study the eruption of undersea volcanoes off the Oregon Coast. The scientists use robotic submarines to examine these massive underwater eruptions and gain a better understanding of the chemical processes at play. Through this research scientists hope to find solutions to the ocean's increasing acidification. A retired Oregon police officer, Mike Full traded his badge for scuba gear in order to search the South Yamhill riverbed for prehistoric fossils. An underwater detective, Mike has collected over 30 percent of the pieces to a giant mammoth skeleton, which other paleontologists call "exceptional". As Field Guide cameras accompany Mike under the water, watch as he makes the discovery of a lifetime right in front of our eyes.

We visit Bagby Hot Springs in the Mt. Hood National Forest and see all the work going on to clean it up and protect the visitors. In the 1990's Bagby had a reputation for alcohol, drugs, vandalism and other crimes. Thanks to improved law enforcement and the work of volunteers from the Northwest Forest Conservancy, families are returning to Bagby. Volunteers have removed trash, maintained trails, educated the public, and restored buildings. Pneumonia is killing off wild bighorn sheep in the Wallowas. Biologists believe that domestic sheep are carrying pathogens that infect the wild bighorns, but ranchers disagree. Watch the incredible lengths biologists go to in their attempt to save the wild sheep and why efforts have ignited a new battle between Oregon and Idaho over how to use public lands. We take you to a beautiful secret garden on Oregon's central coast near Reedsport. Spruce Reach Island is the former estate of O. H. Hinsdale, who planted azaleas, camellias, and rhododendrons on the five acre site, now owned by the BLM. After nearly half a century, there's a good chance the public may finally be able to go there. Come see a volcanic lake in the blast zone of Mount St. Helens in southwest Washington. Videographer Michael Bendixen takes you for an up-close visit to the waters of Spirit Lake, including underwater shots of trout swimming in the lake.

The fisher, a member of the weasel family, once thrived in the Pacific Northwest. But now it’s rare to see one. We take a look at what is happening to the population. There may be fewer than 50 fishers in the cascade range. Fishers are elusive, scientist have set up 16 monitoring stations to try to film the secretive mammal. They also try to capture fisher hair by using sticky tape. Hair samples are then sent to labs for DNA analysis. We follow 'reptile hunters' Chris Rombough and Sarah Petrakis into the wilds of the Willamette Valley and the Columbia Gorge to see just how many snakes and other reptiles we can find. Their finds include a garter snake, gopher snake, racer, ringneck snake, western rattlesnake, and an alligator lizard. You may be surprised to see what's hiding right along the trail. A grand experiment ten years ago attempted to save endangered salmon from feasting Caspian terns. We return to East Sand Island near the mouth of the Columbia River and find it seems to have worked. Except now there’s a new danger from an even larger group of double-crested cormorants who have moved in.

Worldwide, a fungal skin disease called chytridiomycosis is decimating frogs and salamanders. The disease may be responsible for declines in some frog and salamander populations in Oregon, but a biologist finds that an ancient species of frog called the tail frog, which lives only in the Pacific Northwest, remains healthy. We follow the camera crew that produces Google’s Street View feature. Immersive Media is on the cutting edge of video technology. Their camera uses eleven lens to capture 360 degree views. The separate angles are stitched together using powerful software, to give one of a kind views of the world around us. We explore the many different uses of this emerging technology in the virtul world. OFG update looking at what dreams did and didn't come true at the Oregon Garden since we last visited in 1999. After a surge in the vole population, farmers and scientist debate whether the underground critters are harmful or helpful. Voles create elaborate underground tunnel systems that can be destructive to fields and crops. However, using probe cameras, scientists are learning new information about voles and vole holes that suggests voles might play a vital role in nature after all.

This has to be one of our most treacherous but beautiful climbs ever, as three climbers from OSU ascend Mount Washington in the central Oregon Cascades. Using harnessess and ropes, they take us along narrow ledges and up sheer cliffs while trying to avoid falling rocks -- it may be dangerous, but what a view from the top! Do you know how to get slug slime off your hands? What’s that weird hole in the right side of every slug? Learn from an Oregon woman who now loves slugs and welcomes them in her garden. Lee Spencer is a volunteer who spends his time watching over a unique pool, called the Dynamite Hole, on the Umpqua river that is a seasonal home to spawning Steelhead Salmon. He spends twelve hours a day at the river's edge to ensure poachers do not disturb this fragile environment. His work ensures the salmon can finish their treacherous journey up river to lay their eggs so that the cycle of life can continue into the future.

An archaeological team is investigating the wreck of a Spanish galleon -- a transport ship -- that went down with as many as 400 people aboard off the coast at Manzanita about 1690. The cargo from that vessel has been washing up on the Oregon coast for more than a century. Now the search is on for the remains of the ship itself. Watch as John Wayland's electric car, the White Zombie leaves high powered gas cars in the dust as Portland makes a home for the National Electric Drag Racing Association. John claims that his car is the world's fastest accelerating street legal electric car. See this 1972 Datsun time and time again take advantage of the electric motor's full torque in the first instant and continue to break world records. Oregon’s native bumblebees are disappearing. We’ll show you why and what one farmer is doing to help bring them back.

Celilo Falls has been the center of an emotional controversy for more than fifty years... we all know it disappeared when the Columbia River was dammed but some tribal members believe the government blew it up first. You'll see brand new history-making images which might finally settle the matter. There is growing concern over the safety of ancient native Columbia River rock art because of housing developments, vandalism and theft. In the past archaeologists tried to keep the locations secret-now there’s a new effort to actually expose the art to the public as part of an educational campaign that encourages ownership.

Oregon's first hut-to-hut biking route is a doozy of a ride through the backcountry around Mount Hood. We follow the Bright boys who enjoy the scenery even as they struggle to stay on course. A tiny beetle which has devastated entire forests in western North America has returned with a vengeance to Oregon. See how the mountain pine beetle is being dealt with. Colorado's mature lodge pole pine forests have been decimated, see how Oregon foresters hope to avoid the same fate. We’ll show you the latest technology to monitor the health of our streams.

An unusually dedicated group of students from Catlin Gabel school not only volunteer, they pay to spend a week in the woods doing forest restoration. The annual Elana Gold Project serves as a living legacy to a former student who died 15 years before. Follow a biologist down dangerous cliff faces and along 300 foot drops in a quest to identify condor nests along the Columbia. Some of the nests are over 100 years old. It's all part of a research project that may help bring the condors back to the Pacific Northwest. Fifteen years ago Oregon Field Guide reported from the crowded banks of the Deschutes river where litter and chaos ruled. Today, the scene is much quieter. But the management plan responsible for reigning in the chaos over the last decade has also had consequences for business and personal freedom.

The wild pigs invading parts of Oregon not only look dangerous-they are. They are vicious predators that are also doing a lot of damage to the land. We’ll show you what’s being done to try and control them. The Oregon Field Guide team profiles how State and private property owners are trying to control this invasive species. Dr. Jason Dunham a USGS Aquatic Ecologist shows you a side of fresh water ecosystems rarely seen. His secret a stationary underwater camera. Scientist can study specimens in the lab, but could not see how they survive in the wild. The underwater camera helps researchers turn entire fresh water streams into laboratories. See up close shots of Rainbow Trout as well as spawning Steelhead Salmon. Standing water and thousands of hungry birds usually mean death to a farmer’s crops. See why a few people in Oregon are intentionally turning to a new form of farming. They’re growing wetlands. Willamette Valley farmer Mark Knaupp's Mud Slough wetland is such an example. Also called a wetland mitigation bank Mark has partnered with the The Wetlands Conservancy to help restore vital habitat.

Hummingbirds aren’t just fun to watch, they're also on the cutting edge of science. The Oregon Field Guide team heads to the University Portland campus to see how scientists are studying hummingbird flight. Their research is being used in both sports medicine, and robotics. In the future tiny robotic vehicles using characteristics from hummingbird flight could be used for surveillance or in search and rescue operations. As the Malheur National Wildlife Refuge turns 100 years old it faces a serious crisis. An invasion by hundreds of thousands of carp threatens this linchpin in the Pacific Flyway. Trumpeter Swan, Whitefaced Ibis and Egret's are just a few of the many birds you can see at the Malheur refuge. Sadly you will not see many birds at Malheur lake as it has been overrun by introduced carp, but efforts are underway to help prevent further habitat loss. After three years of continuous eruption, Mount St. Helens has gone quiet but has not stopped changing. A new glacier has formed in the mouth of the crater and continues to expand. Scientists from the US Geological Survey have deployed a variety of equipment, allowing them to constantly monitor this dynamic environment. Take a rare trip into the crater to see what scientists continue to learn from the Northwest’s most active volcano.

Find out the truth about cats and birds in the Portland metro area. The Oregon Field guide crew introduces you to Bob Sallinger (Conservation Director for the Audubon Society of Portland), and the Audubon's rescue efforts to save wild song birds from cat predation. To help prevent the thousands of song bird attacks per year. Audubon and the Oregon Feral Cat Coalition have teamed up to promote a Spay/Neuter program. Most people can't put the concept of kayaking and fishing together. But for one Oregon couple, it's the only way to fish. Field Guide journeys to the waters off the beautiful Beverly Beach to see how these two kayak fishermen can get into areas that big boats can't and catch prized lingcod. We head into the ocean for a look at new technology designed to keep our coastline safe for seagoing vessels. See how NOAA (The National Oceanic and Atmospheric Administration) is mapping the coastline off Oregon's coast using multibeam sonar. Join the crew of the research vessel Rainer as they plot the depths of the Columbia River Bar and Grays Harbor in Washington state. As well as the historic wreck of the Admiral Benson passenger ship. The spotted owl may have retreated from the headlines, but it's still in deep trouble. In addition to logging and habitat loss, one of the biggest threat is an invasion of east coast barred owls. A new plan proposes to kill barred owls in certain areas to help give the spotted owls a competitive edge. But will Oregon tolerate shooting one owl to save another?

Learn more about the Eagle Cap Extreme, Oregon's only Iditarod qualifier. Mushers lead their teams through the Wallowa Whitman National Forest in one of two races either the 100 mile or the 200 mile. The Oregon Field Guide crew accompanies the teams and along the way they become part of the story. In addition this episode of Field Guide has some incredibly beautiful shots of the Wallowa's at dawn and dusk. Portland boasts more bicycle riders than most U.S. cities so it's no wonder city planners are doing all they can to make the area as bike friendly as possible. Portland traffic and safety engineers are coming up with innovative ways to prevent accidents. Solutions modeled in bike friendly Holland are migrating to Portland. Bike boxes and designated bike routes are just a couple of the ways Portland leads the nation in bike safety. We check back in with a team of archaeologists searching caves near central Oregon's Summer Lake.

Jim Newman, veteran producer, reporter and "The Voice" of Oregon Field Guide, is hanging up his hiking boots after more than 20 years of covering virtually every corner of the state. This week Field Guide pays special tribute to Jim.

Open Water Swimming

When you think about competitive swimming you probably picture what you see at the Olympics. Long pools. One swimmer per lane. But many people prefer something different: swimming across open lakes. Late in the summer of 2011, Eel Lake near Coos Bay, Oregon featured some serious racing - and a goofy obstacle course.

Pine Butterflies

An exceedingly rare population explosion of pine butterflies fills the Malheur National Forest with a virtual snowstorm in August. The mysterious outbreak may occur for 2 or 3 years and then disappear for 3 decades. The beauty extracts a price: the butterflies, while caterpillars, ate needles off 250,000 acres of trees.

Radon

Public health authorities tell us that radon is the second leading cause of lung cancer in the US, and the highest among non-smokers. But scientists have only been aware of radon as a health hazard since the early 1980s. So, just how big a health risk is radon? We take a look at the geologic conditions that account for radon’s presence in Oregon as well as the current health science, testing and mitigation thinking on the subject.

Chetco River Revisited

Oregon Field Guide journeys back to the remote, Chetco river almost 10 years after the massive Biscuit fire engulfed the Chetco’s remarkable wilderness river canyon. We discover that the river remains as remote and difficult to access than it was before the fire, and yet it’s even more enticing.

Gold Fish

We follow a team of ODFW fish biologists as they try to stop one of the state’s most destructive invaders – gold fish. It turns out that the harmless gold fish most of us had as pets are far from harmless. In fact, if gold fish find their way into Central Oregon’s Crane Prairie reservoir, they could spread throughout the upper Deschutes watershed and destroy the region’s lucrative sport fishing economy.

Muddy Boots

Worms, chickens, bees and gardens of fresh veggies lure children to play and learn outdoors. Portland's Muddy Boots Family Nature Club tackles "nature deficit disorder" by getting kids away from video games into a world of wonder.

Beacon Rock Climbing

Jim Opdycke is the unofficial “mayor” of Beacon rock. He’s climbed this spectacular basalt monolith in the Columbia gorge for over 40 years and has contributed perhaps more than anyone else to the unique traditional, or traditional, climbing culture of Beacon. We join Jim on a climb up the 900 foot face of Beacon Rock, cameras in tow, and learn about the specialized style of climbing known as “trad”- considered the most pure of climbing styles.

Ditch Fish

Willamette Valley farmers learn that in addition to their intended crops, they’ve been raising fish in their fields for years and never knew it. Researchers found young native fish thriving in ditches that fill with water during the winter, an unrecognized habitat until recently.

Newberry Crater Geothermal

EGS, Enhanced Geothermal Systems, hopes to get hot water out of a dry well just outside the Newberry Crater. The experiment hopes to create massive reservoirs two miles under ground. The earth would heat the cold water injected into fissures in the rocks and pumps would bring the hot water back out for energy production.

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.

Kite Festival

Tonight we have a story about a sport that includes floating.. fighting.. and synchronized dancing. That's one way to say: this isn't your grandfather's way to fly kites. Field Guide's Vince Patton and videographer Michael Bendixen found kites from two inches wide to the size of a Macy's Thanksgiving Day Parade balloon… at the largest kite festival in Oregon, in Lincoln City.

Trees and Pollution

Emerging research shows that if plants and trees are planted in certain locations, they can make air pollution worse. The plants emit isoprenes which combine with man-made pollutants to create ozone.

Ultralight Hiking

Clint “Lint” Bunting came to backpacking late in life, but once he took to it he went “all in”. He has hiked over 14,000 miles, including all of the big American Thru hikes: the Appalachian Trail, Pacific Crest Trail, Ice Age Trail and the Continental divide Trail, some of them twice! What’s more, he now hikes for weeks at a time with an 8-pound pack, significantly less than the 40-50 pounds many backpackers typically carry.

Bug Chicks

Kristie Reddick and Jessica Honaker are two entomologists on a mission. They want people to think differently about bugs.

Canoe Journey

Tribal canoe journey and science connect in Salish Sea.

Cape Arago Photo Essay Revisited

Videographer Nick Fisher beautifully captures sunsets, rolling clouds and stunning shots of the beach at high and low tide.

Pacific Crest Trail

Think about what it takes to hike over 2600 miles in a summer. Now, think about what it takes to do it as an 11 year old! That’s what one father/daughter team from Salem did one summer as they hiked the entire Pacific Crest trail from Mexico to Canada. And they shared with us an amazing story of their adventure.

In 2005, just as it seemed Oregon’s urban-rural divide had grown into an unbridgeable chasm, a handful of ranchers from rural Grant county did the unexpected. They invited kids from Portland's Sunnyside Environmental school to live and work along side them and see their side of life. The Urban-Rural exchange has continued every year since. Follow a group of students as they share in both the joy and the misery that comes with real rural life.

Elsie Elzroth is one very dedicated woman. She has spent most of her life helping restore Western bluebird populations to the Corvallis area. The ancient forest that surrounds Portland's Bull Run water supply is off limits to logging after decades of controversy. But questions loom large over fire, climate change, and the risk of leaving a water supply untreated in one of the most pristine watersheds in the nation. Streaked Horned Lark ground-nesting species probably should be extinct by now except that, surprisingly, it has survived in the Portland area because of industrial development.

It takes an expert to build a traditional, seaworthy boat from scratch, right? See how a group of complete amateurs come together to hand-build a traditional style 12 person skin-on-frame "umiak" in just one week. Sixgill Sharks which normally spend their lives at the bottom of the world’s oceans have been found living in the relatively shallow waters of Puget Sound. Recreational divers and researchers lure sixgill sharks in for up close encounters. It’s believed Puget Sound is a sixgill shark nursery: a safe place to give birth and raise hundreds or perhaps a thousand or more young sharks. There has never been a report of a sixgill attack on a human. There’s research to show that the tsunami risk is far more severe than scientists previously thought. We look at Indian oral tradition recounting tsunamis that seem eerily accurate in light of new research. We look at the evidence that proves the risk is great, and what is being done about it in coastal communities.

Knowles Creek used to be a floundering ecosystem, but Charley Dewberry and his team have successfully brought the stream back to life. In their attempts to restore the watershed basin surrounding Knowles Creek, Charley's team's efforts have caused the number of juvenile coho to triple since their restoration began in 1992. Once a controversial project, the scientists who defied conventional wisdom demonstrate how well the project has worked. Turkey Vultures are among the smartest birds in the worlds. Join Oregon’s foremost raptor expert, Jim Anderson, as he takes us on a comical journey from caves to canyons to a roadkill graveyard, all in search of a bird most people dismiss as “just plain ugly”. No, they’re not pretty, and yes, they eat food only after its long dead and stinky, but think about it… what would our world be like it all that dead stuff were left lying around? Update on Oregon State University project to use ocean waves off the Oregon coast to generate power.

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.

The Wallowa River bends again at the 6 Ranch near Enterprise, Oregon. It had been straight for a century. The ranch sacrificed some pasture to restore the river to a more natural path in order to restore endangered fish. Enjoy a little time on the greens with some enthusiastic golfers with special needs. Invasive garlic mustard and Japanese Knotweed are washing like a tide over the west hills toward the Tualatin River. But one Tualatin basin agency is reaching beyond their jurisdiction and sending foot soldiers out to beat back the invaders before they infest the watershed. Two Portland men create a wildly popular bike ride by going out of their way to make it the most difficult ride in the state.

We head to Pacific City to learn more about the growing community of hardcore surfers. There's a place in the coast range so steep, rugged and disorienting that trails don’t go there. Many have trekked in and spent unplanned nights among the ancient trees trying to get out. That place is The Devil’s Staircase, a 30,000 acre area that redefines off-trail adventure. The reward for making it to the heart of this ancient forest, a chance to lay eyes on a rarely visited waterfall and swimming hole along wild, crystal clear Wassen Creek. Washington County wants to expand Hagg Lake to secure enough water for the next 50 years of growth. After years of planning, they’ve hit an expensive snag. New tests show the current dam does not meet today’s standards for earthquake safety.

Every spring, half a million seabirds called common murres come to nest on the rocks off the Oregon coast. As the number of bald eagles has increased in recent years, their attacks have brought havoc to the murre's breeding grounds. Tag along with an Oregon family as they go Geocaching - a game that was born in Oregon and has swept the globe. Using hand held GPS devices players scour the countryside in search hidden treasure. Sometimes hidden in a cave or under a rock these caches contain a log book and some sort of trinket. Players sometimes leave a trinket of their own, if they take what they find, but the real reward is in the hunt for more and more hidden caches. If you’ve taken a drive through the gorge lately, you’ve seen that turbines seem to be sprouting up faster than grass. Wind energy is big business now. Unfortunately, those turbines are taking an unexpected toll on migrating bats.

If you own a boat that runs on gas, maintaining your boat has changed dramatically since the State of Oregon mandated ethanol blend at the pumps. When we think of surveyors, we think about the guy along the road with a laser level. Well there’s another kind of surveyor who’s job is to hike into the wilderness, ensuring that the history of Oregon’s first statewide land survey from the 1800’s isn’t lost to time. Join a 3-day journey deep into the Eagle Cap Wilderness in search of a truly ancient tree. Discovered on a dangerously steep mountain, the limber pine could be among the oldest trees in Oregon – and it’s still alive.

The ocean is turning more acidic as CO2 emissions rise, and shellfish are struggling to survive in the more acidic sea. For those interested in learning more about what is a very complicated topic, check out the following resources; some are fairly academic, others are "plain speak". A tiny, seldom seen bird is discovered alive and well in an unexpected place. Join a biologist who spent more than 300 days tracking dozens of elusive pygmy owls in the middle of city of Portland. They live in Forest Park. Portland hopes to capture some of the 10 billion gallons of rain that flows off 12,000 acres of roofs in the city by promoting eco-roofs. The city and Oregon State University find roofs covered in plants and soil soak up and hold 40 to 55% of the rain that would normally run down storm drains.

The brown pelican has rebounded so successfully, the government has removed it from the endangered species list. Today, the largest pelican roost site in the Northwest sits in Oregon. But when thousands of pelicans lingered too long, winter storms caused severe injuries. Volunteers with the Wildlife Center of the North Coast rushed to save them, nurse them and months later, release them to the wild. Painful, thrilling, crazy -- these are just some of the terms freeriders themselves use to describe their sport. Freeriding is a new twist on a style of mountain biking that originated in Canada where wooden ramps and bridges and logs were laid so bikers could avoid muddy forest trails. Join a group of these daring thrill-seekers in the Oregon forests as they negotiate trails over four-inch logs, high platforms, and bone-rattling jumps. Several endangered Oregon species, including the Kincaid's lupine, rely on oak savannah, a type of habitat that once covered a million acres in the Willamette Valley. Now only pockets of the distinctive landscape of huge oaks and open grassland remains.

A one time dead zone off Oregon’s coast turns out not to be an isolated incident. Oxygen levels are plummeting every summer now. Scientists deploy an army of sensors, including a diving robot explorer, to learn what’s changed in our ocean. For the last 40 years salmon and steelhead have been missing from a place called Whychus creek. But they’re about to come back, and ecologists are getting busy with bulldozers as they prepare for their return. A trip to the Oregon Coast Aquarium for a look at what it takes staff and volunteers to care for thousands of animals.

Arctic White Geese

Hundreds of thousands of migrating geese create a blizzard which blankets the sky and covers farmers’ fields.

Silver Falls State Park

1.5 million people every year make Silver Falls State Park the most popular state park in Oregon. They may be surprised to learn that 80 years ago that a town sat there, the area was full of stumps and the biggest waterfall was a daredevil's playground. Silver Falls was saved by a single-minded photographer determined to protect it for everyone to enjoy.

Zumwalt Cooperation

Despite a century of cattle grazing, Oregon's Zumwalt Prairie remains healthy. A new study by Oregon State University shows low to moderate levels of grazing does not harm the survival of ground nesting birds. The Nature Conservancy's Zumwalt Prairie Preserve also allows grazing in a rare partnership of ranchers and conservationists.
