O Radiant Dark! O Starry Night!

The night sky has inspired us for generations. With the night comes dazzling pinpoints of light, and the Milky Way unfurled in luminous mystery. Nighttime views and environments are among the critical park features the National Park Service protects. Night sky protection enhances qualities of solitude and undeveloped wilderness character that animals depend on for survival, park visitors seek for connections, and many cultural-historical parks require for preservation. In this regard, the NPS recognizes a naturally dark night sky as more than a scenic canvas; it is part of a complex ecosystem that supports both natural and cultural resources.
