Teton Range, Mountain range in northwestern Wyoming, United States.
The Teton Range is a mountain range in northwestern Wyoming with peaks reaching over 12,000 feet (3,600 m), stretching from the southern border of Yellowstone National Park to Teton Pass. The sharp granite spires rise directly from the Jackson Hole valley floor without foothills, forming one of the steepest mountain fronts in North America.
French fur trappers gave the mountains their name in the early 19th century as they moved through the region. The area was later settled by homesteaders and ranchers before parts of it were designated as a national park to protect the landscape.
The French name refers to the three highest peaks, which form a recognizable silhouette when viewed from the east. Local communities have used the surrounding valleys for thousands of years as hunting grounds and routes between the Plains and the Great Basin.
Hiking trails run through the national park to different viewpoints, with many routes accessible during summer months. In winter, nearby ski resorts offer downhill and cross-country options, while higher elevation roads often remain closed.
The mountains formed through tectonic shifts about 6 million years ago and are considerably younger than many other North American mountain ranges. The steep slopes and narrow canyons were carved by glaciers that cut deep grooves into the granite.
