The National Park Service unit extents shown in NPMap products (Places and Park Tiles) do not all pull from the official NPS source, the Land Resources Division (Lands), and should not be considered authoritative.

Lands Data

The NPS unit extents originating with the Land Resources Division shown in NPMap products represent the legislated boundary of each park. The NPS does not necessarily own or hold any interest (easement, right of way, etc.) in all areas contained within these boundaries. Equivalently, the NPS may own an interest in lands outside the legislated boundary.

You can download the official Lands dataset, and view the full metadata, on the NPS Data Store (click through the “NPS Park Boundaries” link on that page). NPS ownership data can also be downloaded for each unit by clicking on the park level “Details” links provided. Boundary and property ownership data are a cartographic interpretation of legislation, deeds, plats, surveys, and other source data. These datasets are not engineering quality drawings and should be used for administrative purposes only.
