Word of the Week: Caldera

Today’s word is:

caldera

Pronounced: cal-DARE-uh

Sciency Definition: The large crater formed when the center of a volcano collapses during an eruption.

Or I could have said: Giant hole in the middle of a volcano.

What’s it do?  Calderas can form incredible lakes, like the one found at Crater Lake National Park in Oregon. Crater Lake was formed when the volcano known as Mount Mazama erupted and collapsed in upon itself. Over the nearly eight thousand years since the eruption, the crater has filled in with rain and snow water, creating one of deepest and clearest lakes in the world.

Example sentenceThe Old Man of the Lake has been bobbing in the waters of the Crater Lake caldera for more than a hundred years!
