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.
Other events include a tour of the Tuff Shed where Grandpa is still forzen; a "polar plunge", for those brave enought to go swimming in Colorado in early March (which generally requires breaking through the ice); a dance called "Grandpa's Blue Ball"; pancake breakfasts; a market showcasing local artists; snowshoe races, and snow sculpture contests. Glacier Ice Cream, headquartered in the nearby city of Boulder, makes a flavor specifically for the festival (named, appropriately enough, Frozen Dead Guy), consisting of fruit flovored blue ice cream mixed with crushed Oreo cookies and sour gummy worms. Tours of the Tuff Shed where Grandpa is still frozen were suspended after 2005, after Grandpa's family "became frustrated with Frozen Dead Guy Days", but were expected to resume with the 2010 celebration.
Although Trygve and Aud filed a complaint against Nederland involving money and naming rights in 2005, Frozen Dead Guy Days is still alive, and according to the official website, the most recent celebration was held March 5th-7th, 2010.
