The Teton Range is a short but spectacular range in northwestern Wyoming, part of the Rockies, famous for the way its jagged peaks leap straight up from the flat floor of Jackson Hole with no foothills to soften them. The Grand Teton, the highest, reaches 13,775 feet (4,199 m), towering more than a mile above the valley and the string of glacial lakes at its base. The sheer, abrupt rise makes it one of the most photographed mountain fronts in the country.

The Tetons are geologically young — they began rising only a few million years ago along a fault that dropped the valley and lifted the mountains, a process that continues today. Glaciers then carved the peaks into sharp horns and gouged the lakes below. Protected within Grand Teton National Park, just south of Yellowstone, the range is a showcase of raw, recent mountain-building.
