THEN: Of the three largest Seattle roofs – the Alki Point Natatorium, a grandstand section of the U.W.’s Denny Field, and the St. James Cathedral dome - that crashed under the weight of the “Northwest Blizzard” in February 1916, the last was the grandest and probably loudest. It fell “with a crashing roar that was heard many blocks distant.” (Courtesy Catholic Archdiocese.)
