Grand Teton National Park
Photographs from Grand Teton National Park. The Tetons are an incredible mountain range. At just over 40 miles long, they are a short range, but there is around 7,000 feet of vertical relief staring at you when you are on the valley floor. The area was designated a national monument in 1929, and then expanded and made into a national park in 1950. When you are visiting Yellowstone, take a few days and head down to the Tetons.
