Bandera Volcano and Cave of Perpetual Ice

Bandera Volcano and Cave of Perpetual Ice

Worth a trip to Grants. The Bandera volcano exploded 10,000 years ago. It is one of the finest examples of an erupted cinder cone and lava field in North America. Bandera spans 1,400 feet wide at the rim and reaches 800 feet deep.

Located in a section of Bandera’s collapsed lava tube, the perpetual Ice Cave's temperature never rises above 31º F. The natural layers of ice have been forming for over 3,400 years. The perpetual Ice Cave is a natural phenomenon made possible by a combination of physical factors forming a natural ice box. Inside the cave, the natural layers of ice glisten blue-green in the reflected rays of sunlight illuminating natural arctic algae.
