tracts of land for the center's 25th anniversary. The largest donated parcel of land was composed of 2,300 acres on the nearby Schunnemunk Mountain, which is the backdrop for many of the center's monumental sculptures, and is an important component of the character of the center and its landscape. Another gift was a one hundred-acre piece of farmland directly adjacent to the center, which has been used to house new additions to the collection. Collection The core collection includes pieces by modern masters, such as Alexander Calder, David Smith, Mark di Suvero, Henry Moore, Douglas Abdell, Isamu Noguchi, Richard Serra, and Louise Nevelson; these are joined with more recent large-scale sculptures by contemporary sculptors, including Magdalena Abakanowicz, Alice Aycock, Andy Goldsworthy, Alexander Liberman, Sol LeWitt, and Roy Lichtenstein. Maya Lin's Storm King Wavefield (2009) is one of the newest additions to the collection, and consists of seven long rows of undulating land forms. Grounds The permanent collection of monumental works is situated throughout the grounds in four main areas: the North Woods, a wooded section in the northeast corner of the property; Museum Hill, an elevated portion on the east edge of the property along the Moodna Creek with views of the surrounding land and its sculptures; the Meadows, which includes the western edge of the park and its entrance; and the South Fields, an open expanse in the southwest portion of the center. The landscape of Storm King Art Center has been in a state of flux from the very beginning. The expanse of rolling hills blanketed with grass and tall trees may look natural, but was carefully molded to form the perfect setting for each of its monumental works of art. The plateau on which stands a 1935 residence, designed to resemble a Norman chateau and later converted to the museum building, was torn apart in the 1950s by bulldozers gathering gravel for the construction of the New York State Thruway; it had to be rebuilt when the art center was established on the grounds. The addition of new site-specific works to the collection also meant constant changes to the center's landscape. Membership Storm King Art Center offers numerous programs and benefits for both members and everyday visitors to the grounds, including bicycles available for rent and guided trolley rides.
