Yes, Yosemite does sit atop a supervolcano known as the Yosemite Caldera. This geological feature is a large, bowl-shaped depression formed by the collapse of land following a volcanic eruption. The last major eruption in the area occurred approximately 760,000 years ago, resulting in the formation of the caldera we see today.
What’s fascinating about Yosemite is that while it’s not an active volcano in the traditional sense, the geological activity associated with the supervolcano isn’t entirely dormant. There are still geothermal features like hot springs and fumaroles in the park, which suggest that there is some residual volcanic activity.
In summary, Yosemite is home to a supervolcano that has shaped much of its stunning landscape. Visitors can enjoy the park’s natural beauty while being aware of the significant volcanic history that lies beneath the surface.
