Robert Morris Earthwork

Robert Morris Earthwork is a 1979 public art earthworks installation in Seatac, Washington by Robert Morris. The area surrounding the piece, a former gravel pit overlooking the Kent Valley outside of Seattle,[1] has rapidly filled in with urban growth, leading to efforts to both protect it and to enhance public access and enjoyment. The earthwork was the result of a King County government symposium titled Earthworks: Land Reclamation as Sculpture. The same symposium also gave impetus to the creation of Mill Creek Canyon Earthworks.[2][3] According to the former director of public art for the city and county, the two pieces are the major earthworks in King County;[4] according to 4Culture, the piece is of "international importance".[2] The site was listed on the National Register of Historic Places in 2021.[5]
