field in upstate New York, chaining surrounding trees and burying a time capsule filled with copies of her haiku. "It was about communication with the earth," Denes said, "and communicating with the future."" Agnes Denes at Artpark, 1977-1979 During her time at Artpark, Denes recreated her Rice/Tree/Burial piece from 1968. In 1977, she planted a half acre (0.2 ha) of rice 150 feet (45 m) above the spot where Niagara Falls had originally formed. The land itself that she worked on was known to have been an industrial dumping ground, which affected the quality of the rice. In 1978, she continued the project by chaining together trees in the forest in the park to symbolize interference with growth. On August 20, 1979, Denes buried a time capsule at 47° 10′ longitude, 79° 2′ 32″ latitude set to be opened in the twenty-third century. The capsule includes microfilmed responses of university students to questions about the nature of humanity. Along with the rice, time capsule, and ceremonial chaining of trees in the park, Denes shot photographs of Niagara Falls for this iteration of Rice/Tree/Burial to "add natural force as the fourth element and fuse the other three".Wheatfield — A Confrontation 1982 Manhattan, Battery Park City landfill After months of preparations, in May 1982, a two-acre (0.8 ha) wheat field was planted on a landfill in lower Manhattan, two blocks from Wall Street and the World Trade Center, facing the Statue of Liberty, sponsored by the Public Art Fund. To create the work, titled Wheatfield — A Confrontation, 200 truckloads of dirt were brought in and 285 furrows were dug by hand and cleared of rocks and garbage. The seeds were sown by hand and the furrows covered with soil. The field was maintained for four months, cleared of wheat smut, weeded, fertilized, and sprayed against mildew fungus, and an irrigation system was set up. The crop was harvested on August 16 and yielded over 1,000 pounds (455 kg) of healthy, golden wheat.Tree Mountain-a living time capsule 1996, Ylöjärvi, Finland A monumental earthwork reclamation project and the first human-made virgin forest, situated in Ylöjärvi, Western Finland.
