During his first term as president, Roosevelt passed the Reclamation Act of 1902 and added more than 125 million acres to national forests, the National Park Service said.
To celebrate, U.S. citizens and residents don't have to pay a fee to enter the national parks.
Other fees, including timed entry or reservation entry at national parks that require them, will still apply.
