In late July 1923, a pivotal meeting among Jackson Hole citizens initiated a conservation effort that ultimately led to the creation of Grand Teton National Park. One hundred years later, the focus has shifted to addressing light pollution in the region. Dr. Samuel Singer, founder of Wyoming Stargazing, alongside local stakeholders, has successfully secured DarkSky International certification for the Town of Jackson and Teton County, aiming to restore the night sky and mitigate the adverse effects of artificial lighting on wildlife and human health. The initiative, which began with a grassroots approach to educate residents, has resulted in significant commitments to reducing light pollution across local governments and businesses, including Jackson Hole Airport, now the first airport globally to achieve Dark Sky certification. This collective effort underscores the importance of preserving the nighttime environment, not just for aesthetics, but for ecological and health benefits as well.
