The national monument is actively working hard to protect this natural resource. Learn more about light pollution and what you can do to make a difference.

International Dark Sky Sanctuary

In 2020, Katahdin Woods and Waters National Monument was certified as an International Dark Sky Sanctuary by DarkSky International. The certification was only the second of its kind in the National Park Service and distinguishes the monument for the exceptional quality of its naturally dark night skies. Katahdin Woods and Waters was the first International Dark Sky Place certified in the state of Maine and in New England. The Natural Sounds and Nights Skies division of the National Park Service has determined that Katahdin Woods and Waters has some of the darkest nights skies east of the Mississippi River.

NPS Rangers and volunteer astronomers at Katahdin Woods and Waters National Monument help measure the darkness of the night skies in northern Maine. Light readings are taken with a Sky Quality Meter. The meter measures how much light strikes the sensor and then converts that amount of light into units of magnitudes per square arc-second. Larger numbers indicate a darker sky. The highest reading so far at Katahdin Woods and Waters National Monument is 21.88!

If you'd like to help collect data on dark skies during your visit to the monument or from your own backyard, go to DarkSky International's website for more information about measuring light pollution.

Tips For Night Sky Viewing

  • Bring a red headlamp or flashlight so that you can safely walk about without hurting your night vision. It takes 20 to 30 minutes for your eyes to fully adjust to darkness.

  • Check the local weather. Clouds can block your view and make for poor stargazing.

  • Check the moon. For the clearest stargazing experience, visit during a new moon for darkest skies. It will be helpful to know the times of moonrise and moonset before your visit.

  • While stargazing can be done year-round, summer is considered the best time to view the Milky Way.

  • Be aware that wildlife are often active at night. Be cautious and alert.

  • Bring a planisphere or a constellation app to assist in your stargazing experience. There are different visible constellations for summer and for winter months.
