Hidden below a massive sea of jagged lava rock is a 1,000 foot long lava tube with ice up to 30 feet thick. Even in the heat of summer, the ice remains permanently frozen, maintaining a temperature between 24 to 32 degrees year-round. Currently it is the largest volcanic cave in the world open to the public.
