National Helium Reserve
The National Helium Reserve, also known as the Federal Helium Reserve, was a strategic reserve of the United States, which once held over 1 billion cubic meters (about 170,000,000 kg) of helium gas. The helium is stored at the Cliffside Storage Facility about 12 miles (19 km) northwest of Amarillo, Texas, in a natural geologic gas storage formation, the Bush Dome reservoir.
