Who Are We?

Our Volunteers

All our IDA Colorado members are volunteers, who are passionate about advancing dark-sky work in Colorado.

Our Organization

The IDA Colorado chapter is a Colorado LLC, and an official part of the International Dark-sky Association.  We enjoy the 501(c)(3) tax-exempt status of the parent group. 

We have a Board of Managers, a volunteer Director who is also the Chair of the Board of Managers, a team of Regional Coordinators, and many members who contribute in other ways.
