Grand Teton National Park

Rising abruptly from the valley floor, the Tetons preserve a dramatic mountain landscape where geology, wildlife, and human history remain strikingly intertwined.

History of the Park

Grand Teton National Park protects one of the youngest and most dramatic mountain ranges in North America. The Teton Range began rising less than 10 million years ago along the Teton Fault, lifting jagged peaks abruptly above the Jackson Hole valley. Unlike many mountain ranges, the Tetons lack foothills, giving them their iconic sheer profile.

Human presence in the region spans over 11,000 years. Indigenous peoples including the Shoshone, Bannock, Gros Ventre, and Blackfeet traveled through the area seasonally to hunt and trade. Later, fur trappers and explorers arrived in the early 19th century, followed by homesteaders and ranchers who left a lasting imprint on the valley’s cultural landscape.

Early conservation efforts were controversial, facing strong local opposition. The original park was established in 1929 under President Calvin Coolidge, protecting the Teton Range itself. In 1950, under President Harry S. Truman, the park was expanded to include Jackson Hole, uniting mountains, valley, and river into the park seen today.

Park Culture

Learn about the local culture surrounding this park.

Culturally, Grand Teton reflects the spirit of the American frontier—where open space, wildlife, and working landscapes coexist. Historic sites like Mormon Row preserve the story of early settlers who farmed beneath the towering peaks, blending human ambition with an unforgiving environment.

The park’s landscape is defined by contrast: sharp granite summits rise above sagebrush flats, while the Snake River winds through wetlands and cottonwood groves. This diversity supports one of the most intact large-mammal ecosystems in the Lower 48, including bison, moose, wolves, and grizzly bears.

Grand Teton National Park feels both raw and composed—its symmetry and scale offering a sense of clarity rarely found elsewhere. It is a place where geology is immediate, wildlife is ever-present, and human history feels small but deeply rooted in the land.
