 As a pioneer of Land Art, Agnes Denes created Rice/Tree/Burial in 1968 in Sullivan County, New York.Acknowledged as the first site-specific performance piece with ecological concerns, it was enacted ten years later on an expanded scale at Artpark in Lewiston, New York.This performance piece involved planting rice seeds in a field in upstate New York, chaining surrounding trees and burying a time capsule filled with copies of her haiku.
