On Presidents’ Day, February 16, 2003, amid a record-breaking snowfall, one half of the Museum’s massive roof collapsed. The collapse occurred as a result of the weight of drifting snow on the western side of the building. Eyewitness accounts depict the drifts nearly six feet in depth. The first alarm was received at approximately 11:40 PM on February 16th. Museum officials responded to find two sections of the 22-sectioned roof collapsed.
