The President can, by Executive proclamation, add any or all lands in a specific tract in township 9 south, ranges 7 and 8 east, Montana principal meridian to Yellowstone National Park. That tract is the area bounded by the park’s north line, the divide around Reese Creek and Mol Heron Creek (and a nearby branch divide), the Yellowstone River, and the western limits of Gardiner, Montana. Only lands that are unappropriated or that the United States acquires under sections 37 to 40 may be added. Added lands must respect any valid existing claims and any reservations allowed by section 39. Except for valid existing claims, land added to the park cannot be taken under the United States mining laws.
