Already the largest in the world, Eastern Oregon’s dark sky sanctuary is expected to grow

PORTLAND, Ore. (KTVZ) -- A sanctuary for stargazing in Eastern Oregon is the largest in the world -- and is set to get even bigger.

In eastern Oregon, the organization DarkSky International declared 2.5 million acres of the Oregon Outback International Dark Sky Sanctuary in the first phase of its process in March. It plans to increase the sanctuary to more than 11 million acres in the next few years.

Damon Motz-Storey, director of the Oregon chapter of the Sierra Club, recently visited the area.

"Anybody who's visited it on a clear summer night or otherwise will agree that it is very spectacular," Motz-Storey observed. "It's a very unique and amazing place to stargaze and get into astronomy."

Motz-Storey pointed out the area is far from urban centers like Portland and Boise, and is sparsely populated. It is estimated more than 2.5 times as many stars are visible than in urban areas. DarkSky International has designated sanctuaries since 2007, and the Oregon Outback is the first in the state.

Motz-Storey emphasized that protecting dark areas is good for wildlife and humans alike because both are affected by artificial lighting.

"These kinds of designations help to spread awareness around people preserving the dark sky for both wildlife and human enjoyment," Motz-Storey stressed. "And also to serve as a little bit of a warning signal to future development to say, 'Hey, this is really worth preserving.'"

Within the Oregon Outback is an area known as the Owyhee Canyonlands. However, Motz-Storey noted that Congress has been unable to pass protections for the unique landscape. A coalition of organizations, including Motz-Storey's, are pushing the Biden administration to declare it a national monument.

"That would pair very nicely with this Dark Sky designation and help to protect everything that's on the ground around the Owyhee Canyonlands, which is just as special as the sky you look up at," Motz-Storey contended.
