Western Slope Skies

What happens when a light switch disrupts billions of years of evolution?

Have you noticed fewer insects around your porch light or fewer splattered bugs on your windshield? You're not alone. Scientists are calling this a new crisis—the "insect apocalypse"—and artificial light at night is a major cause.

The Black Canyon of the Gunnison earned its name from the limited light that reaches its deepest corners during the day. At night, little artificial light, too, intrudes upon its skies, making the canyon a prime location for viewing the celestial wonders above. The annual astronomy festival AstroFest returns again this month to celebrate such sights as well as the Western Slope's precious access to these natural skies.

The sun is shining, the sand feels warm beneath your toes, and you're watching the waves crash over one another. They rise to where you are standing, rushing over your feet and then fall back down. A few hours later, you come back to the same spot- and this time, the waves fall short of reaching you. You pause and start to wonder why... and then, you look up at the sky and spot the moon. There's your answer.
