Teton Range


Located in northwestern Wyoming, Grand Teton National Park protects stunning mountain scenery and a diverse array of wildlife. Rising more than 7,000 feet above the valley of Jackson Hole, the Teton Range dominates the park's skyline. Natural processes continue to shape the ecosystem against this impressive and iconic backdrop.

The park's elevation rises from 6,320 feet on the sagebrush-dominated valley floor to 13,770 feet on the windswept summit of the Grand Teton. Between the summit and plain, forests carpet the mountainsides. During summer, wildflowers paint meadows in vivid colors. Crystalline alpine lakes fill glacial cirques, and noisy streams cascade down rocky canyons to lakes at the foot of the range. These lakes, impounded by glacial moraines, mirror the mountains on calm days. With headwaters north of the park, the Snake River winds its way through the valley and across this amazing scene.

Long, snowy, and bitterly cold winters make the climate of Jackson Hole unforgiving. The coldest temperature ever recorded in the park was -63°F, and snow often blankets the landscape from early November to May. Brief, relatively warm summers provide a respite from the rigors of winter and a time of renewal and rebirth. In cooperation or competition, the plants and animals adapt to this harsh climate and dramatic elevation change as each finds ways to survive.
