Slabsides is the log cabin built by naturalist John Burroughs and his son on a nine-acre (3.6 ha) wooded and hilly tract in 1895 one mile (1.6 km) east of Riverby, his home in West Park, New York. From the time of its construction to the last year of his life, he received many visitors here, ranging from Theodore Roosevelt and Henry Ford to students from Vassar College, just across the Hudson River.
