The Teton Range reflects in the Snake River at Schwabacher Landing in Grand Teton National Park, Wyoming, USA. Lenticular clouds cap the peaks of Grand Teton (13,766 feet or 4198.6 meters) and Teewinot. Grand Teton National Park contains the major peaks of the 40-mile (64 km) Teton Range and part of the valley known as Jackson Hole, Wyoming. The Teton Range began their tectonic uplift 9 million years ago (during the Miocene Epoch), making them the youngest range in the Rocky Mountains. A parkway connects from Grand Teton National Park 10 miles north to Yellowstone National Park.
