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 (3,658 m), including the Grand Teton at 13,770 feet (4,198 m). Seven moraine 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.
