Grand Teton National Park
Grand Teton National Park protects stunning mountain scenery and a diverse array of wildlife. The central feature of the park is the Teton Range, an active, fault-block, 40-mile long mountain front. The range includes eight peaks over 12,000-feet, including the Grand Teton at 13,770-feet. Seven morainal lakes run along the base of the range, and more than 100 alpine lakes can be found in the backcountry. Elk, moose, pronghorn, mule deer, and bison are commonly seen in the park. Black bears are common in forested areas, while grizzlies are occasionally observed in the northern part of the park. More than 300 species of birds can be observed, including bald eagles and peregrine falcons. Located in northwestern Wyoming, Grand Teton National Park preserves a spectacular landscape rich with majestic mountains, pristine lakes and extraordinary wildlife. The abrupt vertical rise of the jagged Teton Range contrasts with the horizontal sage-covered valley and glacial lakes at their base, creating world-renowned scenery that attracts nearly four million visitors per year.
