Oregon Natural Desert Association’s 2026 High Desert Speaker Series invites audiences across Oregon and beyond to uncover the landscapes, geology and cultural histories of eastern Oregon through a pair of engaging online talks this winter. Registration is now open for the free, online public series, which runs from February through March.
The High Desert Speaker Series is designed to inspire a deeper understanding of high desert ecology while cultivating appreciation for the land, water, wildlife and human histories that shape this vast region.
“ONDA is excited to share new perspectives on the high desert,” said Claire Cekander, ONDA’s donor relations manager. “This year, we’ll explore the volcanic forces that built these landscapes and hear a Tribal family history of the region. Whether you’ve been a desert enthusiast for decades or are just curious about this remarkable place, these talks will expand your knowledge and connection to Oregon’s dry side.”
On Wednesday, Feb. 11, the series features Forged in Fire: The Volcanic Activity that Shaped Oregon’s High Desert. This free, online talk covers the powerful volcanic forces that formed eastern Oregon’s iconic landscapes, including the lava flows and ash deposits that created the dramatic landforms that define the region today. Through a photography-rich presentation by Ellen Bishop, author and geologist, attendees will explore how geology created and influenced the high desert’s ecology.
The series concludes on Wednesday, March 11 with A Tribal Family History of the Wadatika’a Band of Northern Paiutes. Dr. Diane Teeman, archaeologist and Tribal elder, will share a rich family history rooted in the high desert though cultural traditions and environmental stewardship. Her presentation provides historical and cultural context that situates the Wadatika’a Band within the long human history of this region. Ryan Houston, ONDA’s executive director, will join to highlight the current steps ONDA is taking to conserve Oregon’s high desert in partnership with local Tribes.
“No matter where you live or how you enjoy eastern Oregon, these talks will deepen your understanding and appreciation of the high desert,” Cekander added.
Both events are held online, free of charge, and open to the public, making it easy for anyone to participate from anywhere. See more information at onda.org/speakerseries/
