William Thomas State Forest is a 1,660-acre (670 ha) state forest in the town of Hill, New Hampshire, in the United States. It is named for Harvard University class of 1945 graduate and B-24 Liberator pilot William H. Thomas Jr. who used his discharge pay to acquire 60 wooded acres and subsequently expanded his holdings to about 1,700. He had visions of a resort development, but retreated to the area in 1987 and donated the lands to the state of New Hanpshire when he died in 2001.^[1] The area reportedly has some double track but no single track trails.
