Frozen Dead Guy Days is an annual celebration held in the town of Nederland, Colorado.
In 1989, a Norwegian citizen named Trygve Bauge brought the corpse of his recently deceased grandfather, Bredo Morstol, to the United States. The body was preserved on dry ice for the trip, and stored in liquid nitrogen at the Trans Time Cryonics facility from 1990 to 1993.
In 1993, Bredo was returned to dry ice and transported to the town of Nederland, where Trygve and his mother Aud planned to create a cryonics facility of their own. When Trygve was deported from the United States for overstaying his visa, his mother, Aud, continued keeping her father's body cryogenically forzen in a shack behind her unfinished house.
