Arizona Had Another Recent Volcanic Eruption!

When people think of Arizona, they tend to not think of volcanoes. Yet, the state contains two active volcanoes, one of which recently erupted in the town of Flagstaff. The volcano I am referring to is called the San Francisco volcanic field, which contains a wide variety of vents not seen elsewhere in the United States. It contains a stratovolcano, explosion craters, cinder cones and more! Scientific evidence just recently re-dated one of its many young lava flows, meaning that this volcano has erupted twice in the last 10,000 years. This video will discuss this volcano, the latest scientific development, and discuss the newly dated SP Crater.
