Montana Chapter IDA To Reorganize

June 11, 2023

The International Dark Sky Association has decided to no longer underwrite individual State Chapters . Our IDA Montana Chapter received its official status as of May of 2019.

Our organization is still active and is continuing its efforts to fight light pollution and protect our Dark Skies. With the reorganization, we will share an affilliation or partnership of one sort or another with the IDA.

The reorganization is not complete as of this writing, but we will announce the launch of "Starry Skies Montana" as soon as we can.

DIL Astroturism Article

November 10, 2019

A Meteor Streaks Over Mount Oberlin in Glacier National Park - Jeremy Weber

The front page of the Sunday November 10, 2019 issue of the Daily Inter Lake prominently featured a wonderful article by reporter Kianna Gardner on the growing astrotourism industry in Montana. The article described how the Flathead's relatively dark skies are becoming an attraction to those looking for a nighttime experience they cannot find at their own place of residence.

The importance of preserving the heritage of our dark skies in Montana cannot be overstated. Reducing the amount of Light Pollution and its many harmful effects in Montana will not only provide economic opportunities across the state, it will benefit all of the state's wildlife that we hold so dear.
