Draft: Dark Sky Maps

What’s a Reserve?

DarkSky International (DSI) certifies areas as dark sky places.

A Dark Sky Community is a city, town, or unincorporated area “with quality outdoor lighting ordinances that educate residents about the importance of dark skies“

A Dark Sky Park includes “publicly or privately owned conservation areas that implement good outdoor lighting and provide dark sky programs”

A Dark Sky Reserve is a land possessing the exceptional quality of starry nights that is specifically protected for its scientific, natural, educational, or cultural value. ”See a list of Dark Sky Reserves here and check out the Central Idaho (U.S.) reserve.


At present, DarkSky West Marin is preparing to apply as a DarkSky Community, and Point Reyes National Seashore is preparing to apply as a DarkSky Park.

Dark Sky West Marin hopes to become part of a DarkSky Reserve someday. A reserve comprises two areas, the “core” and the “periphery.”

“The core of the proposed IDSR must be a public or private land protected for scientific,
natural, educational, cultural, heritage, and/or public enjoyment.”

“The proposed peripheral zone boundary must be singular, contiguous, and completely
enclose the core zone. It may take any shape and may follow logical or
natural geographic features.”
