What this bill would do
This bill, known as the ``Mammoth Cave National Park Boundary Adjustment Act of 2025'', aims to modify the boundary of the Mammoth Cave National Park in Kentucky. It proposes to adjust a specific dollar amount in previous legislation to account for inflation based on the Consumer Price Index. Additionally, the bill authorizes the Secretary of the Interior to acquire approximately 551.14 acres of land. This land is shown on a specific map titled `Proposed Addition' regarding the southern boundary expansion. The acquisition would include the land and any interests in that land for inclusion into the national park.
