Based on a 1970 drawing , '' Study for Floating Island to Travel Around Manhattan Island , '' it is a site-specific public work in which a tugboat tows a large barge covered with earth that is planted with trees and shrubs -- a man-made island of sorts -- around Manhattan , visible on shore at numerous locations along the Hudson , Harlem and East Rivers .
