Lynn Hall's rough-grained slate floor in the 2-story core grand hall on Aug.8, 2022. The floor is natural stone color before Grant and Sparkes tinted it black to make the wear and tear from the deterioration less visible. According to University of Pittsburgh professor Franklin Toker, the floor is identical to Fallingwater's floor. (Alicia Chiang/Post-Gazette)
