#100: Dark skies, our last best place
We’ve all been there—camping or vacationing in the middle of nowhere, the day ends, and suddenly there’s the blackest sky imaginable above, bristling with stars. The West’s vast open spaces mean the darkest skies in the country, and the National Park Service’s Night Sky Program, in Fort Collins, Colorado, is fighting to keep them that way, partnering with towns and cities to limit light pollution that crowds out stars. It’s not a battle for aesthetics alone—studies show that darkness makes us healthier, helping our sleep patterns and boosting immunity. All the more reason to grab your tent and take in the wild night skies.
