Passport Dark Sky Parks PinItem#: 443845
The National Park Service preserves night sky parks to protect natural darkness. Since nearly 70% of mammals are nocturnal, it is important to keep natural light cycles for the continued survival of plants and animals. These parks are also a beautiful experience for visitors to see the night sky unobstructed. Get the Passport Dark Sky Pin to commemorate your trip to one of these amazing sites!
