How National Parks are Designated

National Parks in the United States are designated between the National Park Service (NPS) and Congress. First, the NPS conducts studies to determine the quality of the area and its significance. Then, Congress passes legislation to authorize the creation of a national park, with committees to decide more specific information about the park.

National parks are usually large natural areas with favorable attributes like unique geological features, diverse ecosystems, and recreational opportunities. They are managed by the federal government, with hunting and extractive activities prohibited on the premises. Today, these parks are visited by millions each year and continue to draw more interest from both the tourist and scientific world.

It’s no surprise that the biggest National Park in the US resides in Alaska. Wrangell-St. Elias National Park and Preserve is in south-central Alaska, covering 13.2 million acres. This includes most of the highest peaks in the United States between the Wrangell Mountains and the Saint Elias Mountains. The highest point in the park is Mount Saint Elias, at 18,008 feet.

Shaped by competing forces of volcanism and glaciation, some of the park’s features include the Malaspina Glacier, Hubbard Glacier, and Nabesna Glacier. The Bagley Icefield covers much of the park’s interior, and at the center is the abandoned boomtown of Kennecott, comprising a National Historic Landmark.

Wrangell-St. Elias National Park and Preserve was established in 1980 by the Alaska National Interest Lands Conservation Act following its designation as a National Monument in 1978 by President Jimmy Carter. Today the park is visited annually by over 70,000 people from across the world.

The Smallest National Park in the US

The Gateway Arch National Park in St. Louis, Missouri, is the smallest National Park in the US, covering just 91 acres, which is less than 2% of the size of the next biggest National Park, the Hot Springs. Initially a National Memorial, the Arch commemorates the Louisiana Purchase, the westward movement of American explorers, the first civil government west of the Mississippi River, and the debate over slavery raised by the Dred Scott case.

Other than the Arch, the park also features the Mississippi River, the Old Courthouse, and the 140,000-square-foot museum. The Gateway Arch was completed on October 28, 1965, and has since been maintained by the National Park Service.
