About the Oregon Outback Dark Sky Network
The Oregon Outback, a vast expanse in southeastern Oregon, boasts some of the darkest and most unspoiled night skies in the United States. This high desert region, characterized by its sagebrush plains, rugged mountain ranges and cowboy culture, offers unparalleled stargazing opportunities, free from the intrusion of light pollution.

Formed in 2019, the Outback Dark Sky Network is a grassroots coalition dedicated to preserving the region’s nocturnal environment. Comprising federal, state, and local agencies, non-governmental organizations, tourism boards, businesses, and passionate individuals, the ODSN works collaboratively to protect and promote the area’s dark skies. The ODSN is the administrator for the OOIDSS.
With DarkSky’s March 2024 certification of a 2.5-million-acre portion of the Oregon Outback as an International Dark Sky Sanctuary (IDSS), Oregon became host to the world’s largest IDSS, by far. This certification recognizes the area’s exceptional night sky quality and commitment to minimizing light pollution. The sanctuary plan spans Lake County and parts of Harney and Malheur counties, regions known for their low population density and vast public lands.

With eastern Lake County approved and certified as Phase 1 of the OOIDSS, plans are underway to expand its reach to over 11.4 million acres, expanding the borders to incorporate large portions of Harney and Malheur counties as agencies see fit.
Our Mission
The Outback Dark Sky Network exists to protect and celebrate the region’s exceptional night skies. We are committed to:
1. Preserving natural darkness
for the benefit of wildlife, ecosystems, and human well-being
2. Promoting responsible lighting practices
to reduce light pollution across communities and public lands
3. Supporting scientific research and citizen science
that advances night sky conservation
4. Offering educational opportunities
that connect visitors, students, and local residents to the wonder of the cosmos
5. Promote sustainable and respectful tourism in the Outback
Natural darkness is more than a scenic backdrop—it’s vital to the health of plants, animals, and people. Protecting the dark sky helps safeguard nocturnal habitats, supports migratory species, and reduces the ecological impact of artificial light. For humans, dark skies provide a profound sense of place, a connection to the universe, and opportunities for inspiration, recreation, and learning.
