What is the closest volcano to Iowa?

Answer 1

A number of volcanoes in the U.S. are part of the Ring of Fire. There are two main groups: the Cascade Volcanic Arc, which runs from northern California to British Columbia, Canada; and the Aleutian Arc, which extends along southern Alaska and the Aleutian Islands. The most famous of the volcanoes of the Cascade Arc is Mount St. Helens.

Answer 2

The two distinct mesas 10 miles west of Denver at the foothills of the Rockies are remnants of a lava flow. The prehistoric volcano that produced them erupted about 26 to 65 million years ago as a result of tectonic activity associated with the Rio Grande rift. Today, however, it is an extinct system. The leftovers of the originating eruption is called Ralston dike and the material is being used by a paving company to produce asphalt.
