In art, literature and popular culture Essayist, poet and children's author Aline Murray Kilmer (1886–1941), the widow of poet Joyce Kilmer (1886–1918) lived in Stillwater, New Jersey, for the last 13 years of her life. Her 1785 house, "Whitehall," was built along the Paulins Kill by Abraham Shafer (1754–1820), son of Casper Shafer. It is thought that the setting of her children's book, A Buttonwood Summer (1929), was inspired by Stillwater and the Paulins Kill valley. The 1980 slasher film Friday the 13th was filmed at Camp NoBeBosCo north of Blairstown, New Jersey, in Hardwick Township. The camp's Sand Pond, which stood in for the movie's "Crystal Lake," feeds the Jacksonburg Creek, a tributary of the Paulins Kill. Artist and Queens College professor Louis Finkelstein (1923–2000) created a painting entitled Trees at Paulinskill (c.1991–97) that was among his later pastel works and critically compared to works by French artist and Post-Impressionist painter Paul Cézanne (1839–1906)."Louis Finkelstein: The Late Pastels in the Context of His Artistic Thinking" at Lori Bookstein Fine Art , accessed December 21, 2006.
