16 U.S.C. § 410vv–2 — Administration

(a) In general: The Secretary of the Interior must run the park under this subchapter and the laws generally applicable to National Park System units, including the Act of August 25, 1916, creating the National Park Service. (b) Acquisition of lands: (1) Except as allowed in paragraph (2), the Secretary can only acquire land or land rights in the park by donation. (2) If the Secretary decides protection-zone land is being used, or is about to be used, in a way that doesn't fit this subchapter's purposes, the Secretary may acquire it by other means too, not just donation. (3) The Secretary may acquire historic-zone land subject to terms and easements that let the seller — and the seller's successors — keep managing and commercially running existing hiking and cross-country ski trails, as long as this fits the historic zone's purposes. Any change to how those trails are run needs the Secretary's approval. (c) Historic zone: The historic zone's main purposes are preservation, education, and interpretation. (d) Protection zone: (1) The protection zone's main purpose is preserving the general character of the area across from the Marsh-Billings-Rockefeller Mansion, in a way that still allows current and future uses that fit that goal. (2) The Secretary must work with affected state and local governments and landowners to develop and carry out land-use practices that fit this subchapter's purposes.
