As a Dark Skies park, Glacier excels with astronomy programs. While several programs are drop in, the one is St. Mary offers more education. “Half the Park Happens After Dark” can orient you to the current night sky above Glacier and set you up for stargazing on your own.

This program happens outdoors in the parking lot of St. Mary Visitor Center. Plan to arrive before dark, and bring layers to don as temperatures cool down.

During the program, a park astronomer provides a tour of the night sky. You learn the stories behind a few constellations, identify planets, and garner knowledge about what is overhead. The program ends at 12:30am.

The free astronomy program happens on any night when clear skies prevail or the sky is relatively cloud-free. It is offered from July through September.
