This row of snow covered mountain peaks can be seen across the brush at Grand Teton National Park. Wispy clouds are forming on the right. Grand Teton National Park lies in Northwestern Wyoming about ten miles south of Yellowstone National Park. This park, which includes most of the northern sections of the Jackson Hole valley, contains the major peaks of the Teton Range. The Grand Teton, for which the park is named, at 13,775 feet the is the highest of these peak and Mount Owen is the second highest. The park also contains the Snake River, Jackson, Jenny, Emma, Matilda, Two Oceans, Leigh, Bradley, Taggart and Phelps Lakes, large waterfalls, including Hidden Falls, and several small glaciers. Jackson Lake Dam is located at the outlet of Jackson Lake and was constructed before the creation of the park itself. Grand Teton and Yellowstone National Parks are connected by the John D. Rockefeller, Jr Memorial Parkway.
