Mount Moran, the most massive peak in the Teton Range, dominates the background. Jackson Lake Dam Overlook - Jackson Lake Dam, one mile west of Jackson Lake Junction on the Teton Park Road, raises the level of Jackson Lake a maximum of 39 feet. In addition to being a reservoir, Jackson Lake is also a natural lake formed by an immense glacier that once flowed from Yellowstone National Park. Park on the southwest side of the dam and take a short walk for a peaceful view of Jackson Lake and Mount Moran. A 6-mile hiking trail encircles Jenny Lake.
Parking is limited and the trail becomes crowded, so plan to arrive early or late in the day.
A midday arrival will be frustrating. Follow the road to the small town of Kelly. The Gros Ventre Slide occurred in 1925 when earthquakes and rain caused the north end of Sheep Mountain to break off and dam the Gros Ventre River, forming Lower Slide Lake. From early June to Labor Day a full schedule of activities is conducted daily. Consult a park newspaper, available at visitor centers and entrance stations, or various bulletin boards in the park.
