Jenny Lake is located in Grand Teton National Park in the U.S. state of Wyoming.

[3] The lake was formed approximately 12,000 years ago by glaciers pushing rock debris which carved Cascade Canyon during the last glacial maximum, forming a terminal moraine which now impounds the lake.

Jenny Lake is considered to be a major focal point in Grand Teton National Park, with many hiking trails, scenic boat rides, and quick access to the major climbing routes onto the tallest peaks of the Teton Range.

[2] Jenny Lake is a starting point for many day and overnight hiking trips.

[5] Jenny Lake is named after a Shoshone Indian woman who married an Englishman, Richard "Beaver Dick" Leigh.
