Note: This time capsule was written by Carla Helfferich on Feb. 15, 1989, soon after the legendary January 1989 cold snap broke. For six straight days in late January that year, Fairbanks’ high temperature stayed at or below minus 40. On Jan. 25, temperatures briefly rose to a balmy 31 below zero before dropping to minus 51. Helfferich explored one consequence of that cold snap: spooky garage door malfunctions. — Sara Wilbur
