Where is Jenny Lake located and what national park is it in?

Jenny Lake is located in Grand Teton National Park in northwestern Wyoming, USA. It sits at the base of the Teton Range and is one of the park's most popular destinations, accessible via the Jenny Lake Road off the main park loop.

How deep is Jenny Lake and how large is it?

Jenny Lake covers approximately 1,191 acres and reaches maximum depths of about 256 feet, making it one of the deeper and larger lakes in Grand Teton National Park. Its size and depth are the result of glacial carving during the last ice age, with the lake formed behind a terminal moraine.

How was Jenny Lake formed?

Jenny Lake is a glacially carved lake, formed when a glacier advancing from the Teton Range excavated a deep basin that subsequently filled with water after the glacier retreated. The lake is dammed on its eastern side by a terminal moraine—accumulated rubble deposited at the glacier's furthest point of advance.

Can you take a boat shuttle across Jenny Lake?

Yes, a seasonal boat shuttle service operates on Jenny Lake, transporting visitors from the east shore to the west shore near the start of the Cascade Canyon trail. The shuttle reduces the round-trip hiking distance to popular destinations like Inspiration Point and Hidden Falls, both of which are accessible from the west-side dock.
