the Visitor Center will be on restricted hours, we have installed an
“Iron Ranger” (located at Visitor Center Parking Area Kiosk) to
allow visitors to pay fees for the scenic drives when the Center is
closed. Visitors with a current Bison Range season pass, a Federal
Recreation Area Pass, or their Federal Migratory Bird Stamp (Duck
Stamp) will not need to use this. These passes may be purchased when
the Visitor Center is open.
