Jenny Lake, Grand Teton National Park. Wyoming

Jenny Lake, formed by melting glaciers about 60,000 years ago, is a beautiful blue mountain lake set in the heart of Grand Teton National Park, at the base of Teewinot Mountain. On the west side, the lake touches the Teton Mountain Range. The lake is about 260 feet deep at the deepest point. Jenny Lake is the starting point for numerous hiking trails in the area, including Inspiration Point and Hidden Falls. There is a 6.6-mile long trail that winds around the entire lake.
