Each summer, sunlight enters the Solstice Window at sunrise on the solstice and collimates a shaft of light across the Museum’s Great Hall, projecting the form of a spiral onto the opposite wall. The Center of Southwest Studies, located on the campus of Fort Lewis College in Durango, Colorado, opens before sunrise on the day of the solstice (around 5:45 am). The public is invited to come be a part of this annual celebration. More information is at The Center of Southwest Studies. Thanks to Don Asquin, astronomer extraordinaire, for collaborating on this project. Video by Christina Knickerbocker.
