When I first moved to the Claycomo area over twenty years ago, I was fascinated when one of the job interviews that I had applied for was located in the "caves." SubTropolis is a 55,000,000 square foot man-made cave in the bluffs above the Missouri River, and is claimed to be the world’s largest underground storage facility. At places, it is 160 feet beneath the surface, has a grid of 16 feet high, and 40-foot wide tunnels separated by 25-foot square limestone pillars created by the room and pillar method of hard rock mining. It contains almost seven miles of illuminated, paved roads and several miles of railroad track. It naturally maintains temperatures between 65 and 70 degrees Fahrenheit year round. It is said that some companies are looking at ways to utilize space, such as this for everything from mushroom farming to crude oil stockpiling.
