The Destroyed 10,000 Foot Volcano in New Hampshire; The Ossipee Caldera

One of the largest calderas on the planet is located within New Hampshire. This caldera today encompasses the entire Ossipee Mountain Range, which was once the site of a 10,000 foot tall volcano. The volcano eventually collapsed, producing a massive depression in the ground. The ancient volcano is today a mere fraction of its original height, which was built up due to an underlying hotspot in the mantle, termed the Great Meteor or New England Hotspot. This video will discuss this volcanic complex, which is one of the little known volcanic features within New England.
