Geothermal Features

Half of the world's geothermal features are in Yellowstone. Yellowstone is actually the caldera of  the largest supervolcano on the continent.  Though it has only erupted a few times in the last couple of million years, it is nevertheless considered an active volcano.

We visited Old Faithful on one of the two (?) rainy days of our three week vacation
