A relatively new geologic feature is found at this national monument. Starting some 15,000 years ago with the latest eruption a mere 2,000 years ago the great rift provides proof of the volcanic nature of our planet. Large fields of cooled lava are dotted with mini volcano cones which are actually blowholes for releasing gas captured under the molten flow of lava. This area is along the Snake river Plateau in Idaho.
