The account
Run by the US Navy, it suffered many problems, including a fire and coolant leaks; after it closed, the radioactive soil around its tanks was dug up and shipped to Port Hueneme in California. Its existence shows that Antarctica did host a secret-sounding military technology, though one documented in public records.
