The Grand Teton National Park’s 485 square miles include the major portion of Wyoming’s Teton Range and the valley of Jackson Hole. Together the mountain range and valley frame eight large lakes, and many smaller ones, glaciers, numerous snowfields and extensive pine, fir and spruce forests. The Tetons are amongst the youngest mountains in the continent. The highest peaks are Grand Teton, 13,770 ft, Mount Owen, 12,928ft, Middle Teton, 12,804ft, Mount Moran 12,605ft, South Teton, 12,514ft, Mount Teewinot, 12,325ft and Thor Peak, 12,028ft.

Few mountains have a greater variety of glaciated canyons than the Tetons. The block-faulted mountains of this alpine park resulting in isolated peaks with sheer sides are of a type rare in the United States. Part of the park area lies above the tree line, which is at 10,000 feet. The park offers a number of exciting viewpoints from Oxbow Bend Overlook in the north to Jenny Lake and Moose Junction in the south.

The Snake River runs the length of the park and offers excellent locations for photography. The Snake River Overlook was made famous by Ansell Adams fine monochrome print. This locality offers a superb spot for sunrise photographs. To the east of the park on Antelope Flats Road stands the Moulten Barn, a remnant of Mormon occupation. The area is only accessible on foot during winter months.

The park supports a large amount of wildlife and regularly seen in the area are moose, beaver, raven and the large herd of bison that graze the grasslands to the east of the park.
