The Lease to obtain lands for the park:  Early attempts to establish a national park in American Samoa failed when there seemed no way for the government to acquire traditionally owned village lands for a public park.  Decades later the High Court of American Samoa and the U.S. Congress developed a compromise allowing lease of the necessary lands for this park.  The lease agreement colors many of the visitor and park management practices that can occur within the park.  View the lease agreement as a pdf file.
