Discover America’s 63 National Parks: A Journey Through Pt.1 (#1-21)

Yellowstone: The World’s First National Park

Established in 1872, Yellowstone National Park is not only the first national park in the United States, but also widely regarded as the oldest in the world. The park is located primarily in the northwest corner of Wyoming but also extends into Montana and Idaho. With over 2.2 million acres, Yellowstone is the second largest U.S. National Park outside of Alaska and boasts arguably the most impressive array of wildlife.

Unrivaled Hydrothermal Features

Yellowstone sits atop a supervolcano and was initially created to protect the abundant hydrothermal features that lie within its boundaries. It is home to the world’s greatest concentration of geysers and the Grand Prismatic Spring, which gets its color gradient from thermophilic bacteria that flourish towards the water’s edge. Nestled in the Rocky Mountains at 8,000 feet above sea level, Yellowstone is a biodiversity hotspot.

Iconic Wildlife of Yellowstone

Yellowstone is home to an impressive array of wildlife, including elk, herds of bison, pronghorn, amphibians such as the western tiger salamander, and birds such as the great horned owl.

Grand Teton: Majestic Peaks and Rugged Beauty

Situated to the south of Yellowstone, Grand Teton National Park was established in 1929 to protect the Teton Range and several lakes that sit at the foot of the mountains. The Tetons is a smaller range within the Rockies, whose highest peak, Grand Teton, rises to almost 14,000 feet.

A Unique Geological History

Although the Teton Range is one of the youngest in North America, having only been uplifting for a mere 10 million years, the rock from which it is formed is some of the oldest in North America, dating back 2.7 billion years. A mixture of metamorphic gneiss and granite produce the spectacular dark grey peaks for which this range is famous.

Wildlife in Grand Teton

The wildlife in Grand Teton is equally stunning, with both grizzly and black bears roaming the forests alongside moose, whose range extends not much further south. There are also over 10,000 species of insects in this region, such as the swallowtail butterfly, which play an important role in pollination.
