Grand Teton National Park is part of the Rocky Mountains, with its mountains rising from the floor of Jackson Hole without any foothills along an active fault mountain system 40 miles long by 7 to 9 miles wide. The area is considered to be one of the most picturesque places in North America and is home to moose, coyotes, black bears, badgers, bald eagles, elk, martins, squirrels and several species of trout.
