Jackson Lake

Jackson Lake is a large reservoir in the northern section of Grand Teton National Park, sitting at about 2064 meters elevation surrounded by mountain peaks and forest. The water spreads across several kilometers and is bounded by steep slopes that rise directly from the shore.

The lake formed about 10,000 years ago when glaciers retreated and left behind a natural moraine that trapped melting ice water. This geological process shaped the landscape of the northern park area as it exists today.

Native American tribes established their presence around Jackson Lake for thousands of years, using its resources for fishing and gathering activities.

Visitors can access the lake at several points along the shore, where camping areas and facilities are scattered throughout the park. The season for most outdoor activities runs from spring through fall, when weather and facilities are generally available.

Researchers monitor the lake closely to study the risk of glacier lake outburst floods and assess hazards in the region. This ongoing research helps scientists understand how such events might occur in other mountain areas around the world.
