This Is the First U.S. County to Be Fully Dark Sky Certified—and It Just Added the World's First Dark Sky Airport

The night skies over Wyoming have seen some major milestones in recent weeks.
In late April, Teton County—home to Jackson Hole Mountain Resort, Grand Teton National Park, and part of Yellowstone National Park—made history as the first county in the world to be certified as an International Dark Sky Community by DarkSky International. Just 10 days later, Jackson Hole Airport (JAC) followed suit, becoming the first airport ever to earn the designation as an International Dark Sky Place, a recognition typically reserved for parks, preserves, and remote communities.
But these "world's first" designations come as little surprise when you consider the data. Light pollution is the enemy of dark skies, and Teton County's small, low light-impact communities help keep night skies pristine. The town of Jackson, the county's largest population center, has just over 10,000 residents, while the tiny community of Kelly is home to only 254. Add to that the vast stretches of protected open space—including all of Grand Teton National Park, 40 percent of Yellowstone, parts of three U.S. National Forests, and the 24,700-acre National Elk Refuge—and it's clear why Teton County is leading the way in night sky conservation.
Similarly, the Jackson Hole Airport is the only commercial airport located within a national park, which incentivizes the airport to take care of the area's natural resources—dark skies included. 'JAC staff dedicated hundreds of hours to updating lighting fixtures and programming to adhere to responsible lighting practices," DarkSky International said in a release. "These measures will not only improve the stargazing experience, but they will also help protect the wildlife in Grand Teton National Park as well as surrounding areas that rely on the natural nocturnal environment to thrive.'
The state's journey towards these dark sky designations started in 2013 when Wyoming Stargazing began hosting weekly public stargazing programs.
'The stars are literally etched into our DNA,' said Samuel Singer, the executive director of Wyoming Stargazing, in a press release. 'If dark night skies ever disappear, we will have lost a part of what it means to be human.'
Teton County and Jackson Hole Airport's efforts to improve lighting policies not only improve the experience of every visitor that will come to its two national parks, but every creature living within them as well.
'This community commitment to ensuring future generations of park visitors and county residents all have access to the beauty Wyoming skies offer in the night is something we are all proud to be a part of,' said Chip Jenkins, a Grand Teton National Park superintendent, in a statement.
