Lake Tahoe was formed over 2 million years ago during the Ice Age. Glacial activity, volcanic eruptions, and faulting processes shaped the basin into the iconic lake we know today.
Geological Origins: The Tahoe Basin was formed by tectonic plate movements and volcanic activity.
Glacial Activity: Glaciers carved out the lake’s basin.
Age: The lake is estimated to be over 2 million years old.
