About the IDA Utah Chapter

The Utah Chapter of the International Dark-Sky Association works to protect Utah’s heritage of star-filled night skies. The chapter is an all-volunteer, educational group working with businesses, towns, municipalities, groups and individuals to keep our rural night skies dark and full of stars, and to help Utahns tackle light pollution issues in our towns and cities.
