16 We thus move on to the second question we posed in Sturgeon I., concerning the Park Service’s power to regulate even non-public lands and waters within Alaska’s system units (or, in our unofficial terminology, national parks). The Service principally relies on that sort of ownership-indifferent authority in defending its decision to expel Sturgeon’s hovercraft from the Nation River. See Brief for Respondents 16–18, 25–32. And we can see why. If Sturgeon lived in any other State, his suit would not have a prayer of success. As noted earlier, the Park Service has used its Organic Act authority to ban hovercrafts on navigable waters “located within [a national park’s] boundaries” without any “regard to… ownership.” 36 CFR §§2.17(e), 1.2(a)(3); see supra, at 10–11. And no one disputes that Sturgeon was driving his hovercraft on a stretch of the Nation River (a navigable water) inside the borders of the Yukon–Charley (a national park). So case closed. Except that Sturgeon lives in Alaska. And as we have said before, “Alaska is often the exception, not the rule.” Sturgeon I., 577 U. S., at __ (slip op., at 14). Here, Section 103(c) of ANILCA makes it so. As explained below, that section provides that even when non-public lands—again, including waters—are geographically within a national park’s boundaries, they may not be regulated as part of the park. And that means the Park Service’s hovercraft regulation cannot apply there.
