Friday, November 17, 2023—Potluck/ExploraTalk-Marli Miller: Geology Roadside view of OR & WA

Assembling the Northwest: A roadside view of Oregon and Washington’s geology With its spectacular mountain ranges, lush valleys and tumbling rivers, the Northwest landscape attracts nature lovers and travelers from around the world. But the rain-soaked coast range, snow-covered volcanoes and expansive high desert didn’t appear overnight. They formed through a variety of geologic processes over millions of years. On November 17, geologist and photographer Marli Miller will outline the geology of Oregon and Washington as seen along our federal and state highways. Beginning with our plate tectonic setting, she will describe the process of continental growth that forms the underlying but diverse basement of the region, followed by a photographic “roadtrip” up the Columbia Gorge to illustrate younger features. You will leave the Lodge eager for your next road trip! Miller is the author of Roadside Geology of Oregon, 2nd Edition, Roadside Geology of Washington, 2nd Edition, which she wrote with Darrel Cowan of the University of Washington, and most recently Oregon Rocks! A Guide to 60 Amazing Geologic Sites. She is a Senior Instructor II in the Dept. of Earth Sciences at the University of Oregon. Copies of her books will be available at the event. You do not need to be an Obsidian member to attend. All are welcome! Signing up here is not necessary, but it is helpful.

Tuesday, October 15, 2013—Tebenkof Bay Wilderness

The October 15 ExploraTalk, featuring southeast Alaska's extremely remote Tebenkof Bay Wilderness, will be presented by science writer Valerie Rapp, who explored it on a kayak expedition in June. Valerie was invited on the expedition to be a visiting writer in Alaska's Voices of the Wilderness program. Tebenkof Bay Wilderness, part of a larger wilderness complex of islands and straits sprawling across the waistline of the Tongass National Forest, is so remote that no more than 50 people visit it a year. There are zero miles of hiking trails, but it does have abundant sea otters, bald eagles, and humpback whales. Valerie will use the story of her trip to start a discussion about who will be the future constituency for Tebenkof and other little-known wildernesses, and what we want our legacies to be fifty years from now in terms of wilderness values. Valerie is the author of six books, including "What the River Reveals" (2008 ValGene Press), and numerous scientific publications. She has also collaborated with artist Jennifer Williams on educational installations using images and words to explore healing our wounded watersheds, ecological recovery at Mt. St. Helens, and the importance of salmon.

You see them in yards, gardens, and on your hikes—the dragonflies and damselflies live most of their lives underwater in a carnivorous nymph phase seeking prey, then as adults they dominate life over and near the water. Discover insects in Oregon whose ancestors were here before the dinosaurs, who can live for five years, fly 35 mph, and truly eat ‘on the fly’. Thirty-seven species have been recorded in West Eugene. Cary Kerst, an aquatic entomologist retired from a career in environmental sciences, will provide a photographic introduction to the life history, habits, and behavior of these fascinating insects. He and co-author Steve Gordon won the West Eugene Wetlands Partnership Award for their research and writing of Dragonflies and Damselflies of the Willamette Valley, Oregon: A Beginner’s Guide.

Thursday, September 16, 2010. The Kiger Mustangs and Other Natural Wonders of Steens Mountain. Bob Petit, local nature photographer, will talk about his adventures photographing the wild and rugged beauty of Steens Mountain and his special passion for the Kiger Mustangs whose history dates back to the discovery of the New World by the Spanish Conquistadores. They were thought to be extinct for a hundred years but were rediscovered in the 1970s. Their blood line is remarkably pure compared to other wild horses, mainly because they are extremely elusive and live in the remote Steens Mountains of Southeast Oregon.

Kit will also describe the work of the CRC, which is a non-profit Nature Center and Wildlife Hospital in South Eugene, specializing in raptors. This community supported and volunteer driven organization has been rehabilitating wildlife and educating the public for 20 years. With over 60 non-releasable birds of 33 native species, RC’s nature center has an unparalleled ability to engage visitors of all ages from around the world. CRC works with approximately 200 raptors each year in its hospital. Kit has an M.S. in biology, taught at LCC and is now leading the CRC’s Education Team.

Tuesday, January 20, 2009. Klamath Basin Migratory Birds. Please join Oregon Wild’s Klamath Campaign Coordinator, Ani Kame’enui, on Tuesday, January 20, at 7 p.m., in exploring the beauty and diversity of an Oregon wonder. Tucked into the southern reaches of the state, the Klamath Basin plays host to a myriad of migratory bird species every year. This is a place where snow geese congregate in the tens of thousands, American White Pelicans dip their slender beaks in search of fish, and bald eagles gather in their largest numbers in the continental United States.

In this slide presentation, we will rediscover the bold beauty and harsh challenges faced by these crown jewels of the West. Come share in the spectacular images of professional photographer Brett Cole as we tour the Lower Klamath National Wildlife Refuge, which is celebrating its 100th anniversary this year as the oldest migratory waterfowl refuge in the nation.

Ani, daughter of Obsidian member Brenda Kame’enui, will travel from her Portland headquarters for our program. Ani says that Oregon Wild’s role in the Klamath Basin is critical to see that management is done to the highest environmental standard possible.

HOOKED ON ADVENTURE: Empowerment in the Outdoors. Why adventure? Instead of painting or reading, we spend our weekends experiencing such natural wonders as bug bites, hypothermia, gastrointestinal issues. And regardless of past discomfort and cost, we still set out the next free weekend, needing nature like one needs air.

As part of a Psychology thesis project, City of Eugene River House Outdoor Program instructor Heather Brule asked outdoors people what got them hooked on adventure. In this presentation of their responses, she will explore the idea of perceived control and how adventure promotes personal empowerment. Heather recently completed UO’s Outdoor Pursuits Leadership Program.

McKENZIE RIVER TRUST and AUDUBON’S TEN MILE CREEK SANCTUARY. Joe Molle, executive director of the McKenzie River Trust, will give us a close-up view of the McKenzie River Trust’s activities. He will feature a new Trust project restoring historic riverine environment to its natural state on an Oregon Coast site adjoining Portland Audubon’s Ten Mile Creek Sanctuary near Yachats. Joe came to the McKenzie River Trust from Montana, where he worked with grizzly bears. This portion of the program is sponsored by our Conservation Committee.

Obsidians will have a rare opportunity to walk or hike the restoration site and the Ten Mile Creek Sanctuary on June 27 when two Obsidian Conservation hikes will be led by Paul Engelmeyer, Audubon’s Sanctuary manager and a McKenzie trust representative. Neither property is usually open to the public.

Tuesday, January 22, 2008.  Where�d Eugene Come From? In the last several years a group of local scientists has been making some fascinating discoveries about the origin of the unique soil found in the Willamette Valley. It is this soil that makes the West Eugene Wetlands habitat what is it today.

Cascadia Wildlands has been instrumental in educating the public about the negative effects of the changes.

Tuesday, April 15, 2008. Bruce Klepinger, president of IBEX Expeditions, will show slides on “Exploring the Himalayan Arc”. He says “Walking through a place and experiencing its people on a one-to-one basis provides insights about—and a tangible and visceral connection to—the land, the people who reside there, and the interaction between land and people that is obtainable through no other means.

“One of the world’s great natural laboratories is the Himalayan Arc, which drapes across Asia from deep in Afghanistan on the west to Burma and Yunnan and Sichuan on the east, a span of more than 3000 miles. This immense arc includes the 1500 mile Great Himalayan Range, the historically critical Hindu Kush and Hindu Raj, the awesome Karakorum, the unknown Tien Shan and the many ranges of the Trans-Himalaya.

“In the course of this visual presentation, you’ll have the opportunity ‘to walk and explore’ the length and breadth of these mountains, seeing images collected over nearly four decades. You’ll glimpse Muslims, Hindus, Buddhists, Sikhs, Jains, Christians and many others in the locale that has led them to flourish. You’ll be able to trace ancient trade routes that cut across the great barrier and witness how the exchange has transformed places. You’ll observe how isolation and the land itself have influenced tribal customs, architecture and virtually every facet of life and vice versa. You’ll see that the Himalayas still play a critical role for the remainder of Asia.”

Tuesday, May 20, 2008.

Tuesday, January 9, 2007.  Ice-age Fossils Tell Story. Obsidian member and geologist Peter Rodda will present a fossil story.  Twenty-five thousand years ago, during the last glacial period, what is now San Francisco Bay was a broad, well-watered valley teeming with large, now extinct, animals - mammoth, bison, ground sloth, sabretooth cat, etc. A long episode of global warming changed all that and over thousands of years produced the present environment.  Fossils, found on-land and offshore, are keys to unraveling this history.  One important piece of evidence, from an excavation in downtown San Francisco, was made available only through some undercover work--a bit of paleontological skullduggery.
    About Peter: Ph.D. in Geology from UCLA; 13 years as research geologist for the Texas Bureau of Economic Geology, Austin; 26 years as Curator of Geology at the California Academy of Sciences, San Francisco; retired in 1997 and moved to Eugene; continuing research on California and Oregon fossils.
