our
story

For over 50 years, Sunriver Nature Center & Observatory (SNCO) has been a cornerstone of education and scientific exploration in Sunriver. Nestled on an eight-acre campus that is home to both the Sunriver Nature Center and the Sunriver Observatory, we offer immersive learning experiences that connect visitors to the wonders of the natural world. Our campus features a unique confluence of pine forests, wetlands, and meadows that form a rich ecological tapestry for exploration, discovery, research, and reflection.

The Beginning of Something Incredible

Sunriver founder John Gray envisioned an environmental education center as a key element of the developing Sunriver community. That vision became a reality with the establishment of the "Ecologium," and the appointment of revered Central Oregonian Jim Anderson as its first naturalist. Jim’s early leadership laid the foundation for SNCO’s enduring commitment to conservation and education, fostering a deep appreciation for the region’s diverse ecosystems. His passion and dedication not only shaped the organization’s early programs but also inspired generations of nature enthusiasts, scientists, and educators who continue to carry his legacy forward.

In 1973, Jay Bowerman was named SNCO’s second resident naturalist, a role he would passionately serve in for over four decades. He retired as Principal Researcher in 2017, leaving behind a lasting legacy. Jay’s contributions—spanning research, education, and program development—were instrumental in shaping SNCO into what it is today. Among his many achievements, he and his wife Teresa founded the Second Tern Thrift Store, which has grown into a vital source of support for SNCO’s programs and operations. Thanks to their vision and dedication, Second Tern continues to thrive, providing essential funding while fostering a spirit of sustainability and community involvement.

Bringing the Stars to Our Backyard

Our Observatory, built in 1991 by Larry Pratt, was then led by local astronomy legend Bob Grossfeld for over 30 years. Bob, one of NASA’s original ‘Solar System Ambassadors,’ spearheaded the effort that resulted in Sunriver being named the first “International Dark Sky Place” in Oregon. Under Bob’s leadership, our humble observatory grew into a premier destination for stargazers, now home to the nation’s largest collection of telescopes available for public viewing. His passion for astronomy and dedication to public education have left an indelible mark, inspiring countless visitors to look up, explore, and connect with the universe.

In 2018, SNCO celebrated its 50th anniversary, marking half a century of dedication to environmental and astronomical education. By this time, the Oregon Observatory had grown into the largest publicly accessible observatory in the United States, earning designation as a NASA affiliate and housing an impressive array of telescopes for public viewing. This milestone not only honored SNCO’s rich history but also reinforced its role as a leading institution for science education, conservation, and discovery—continuing to inspire visitors of all ages to explore the wonders of the natural world and the cosmos.
