On April 27th, 1993, New York State’s largest landslide in 75 years occurred in the Tully Valley, destroying three homes and covering an area of 1,500 feet of Tully Farms Road with mud 15 feet deep. A combination of events led to the slide, including the record snowfall during the winter of 1992-1993. Three people were rescued from their home by helicopter with no serious injuries reported. Homeowners were allowed to return to their homes two weeks after the slide, though Tully Farms Road continued to be blocked for several months as authorities cleared debris.
