A 2.5 million-acre swath of southern Oregon has been named the largest Dark Sky Sanctuary in the world. The region, which on Monday was officially named the Oregon Outback International Dark Sky Sanctuary, comprises the southeastern half of Lake County, including Hart Mountain, Lake Abert and Summer Lake. Future plans include expanding the sanctuary to 11.4 million acres across Harney and Malheur counties. The designation was given by DarkSky International, an organization dedicated to protecting the nighttime environment and preserving dark skies through environmentally responsible outdoor lighting. The project is the work of the Oregon Dark Sky Network, an ad-hoc group of state, local and federal officials, private individuals, business owners and tourism agencies.
