Green's Prairie Cemetery contains the graves of pioneer settlers of York, Adams, and Primrose Townships, who began settling here in 1838. Many came from New York state, for which York Township was named. Polly Crowel was the first person buried here in 1845, and Anna Walker was the last in 1917. Tall-grass prairie once covered 5,000 acres of York Township, including the surrounding rolling hills, but because this burial ground was never plowed, its one-acre remnant of deep-soil prairie survived. Less than one percent of Wisconsin's original prairie still exists, and the cemetery contains sixty species of prairie plants genetically descended from ancient stock. Yearly burns help preserve the cemetery much as it appeared in the 1800s, when settlers chose it as a burial place for their loved ones. The cemetery was named for William C. Green, the second settler in York Township and the first superintendent of Green County Schools. Also buried here is Albro Crowel, the first settler of the village of Postville. The veterans buried here include one Black Hawk War veteran, James Biggs; four War of 1812 veterans, Elisha Gorham, Robert Peebles, Nathan Sherman, and David Ash; and six Civil War veterans, Amos Conkey, Rosel Crowel, William Sherman, John W. Stewart, Joel Walker, and John Westcott. Civil War veterans George Thomas and Henry Gorham, whose bodies were lost in battle, also have markers here at their families' request. Josiah La Follette, father of Wisconsin Governor and U.S. Senator "Fighting Bob" La Follette, was later reinterred in Madison's Forest Hill Cemetery at his wife's request.
