Jenny Lake, Glacial lake in Grand Teton National Park, United States.
Jenny Lake is a glacial lake in Grand Teton National Park with clear water reflecting sharp granite peaks. The water extends across a broad area and reaches considerable depths, surrounded by steep mountainsides and open shoreline.
The lake was named in 1872 during the Hayden Expedition, a geological survey mission exploring the Teton Range. The name honors Jenny Leigh, wife of a guide who assisted the expedition.
The visitor center here occupies a 1920s studio building and displays photographs and artworks showing how the Teton Range has been seen through different eyes. These collections reflect the long tradition of artists and photographers drawn to capture this landscape.
The shore is accessible by hiking trails, or you can use boat shuttles to reach higher viewpoints and waterfalls more quickly. The best visiting time avoids the extremes of deep winter and peak summer heat.
Thermal features on the lake bottom create zones of warmer water that remain unfrozen through winter months. These hidden heat sources are one of the lesser-noticed natural phenomena visitors rarely learn about.
