Secret Activities in Antarctica

Huge military expeditions have explored Antarctica and billions of dollars are spent each year to maintain expensive bases there. The United States maintains three large bases in Antarctica in a Polar program with 3000 people, plus military transport support. McMurdo Station has 1650 personnel, was built by the US Navy, and happens to exist near an active volcano. What are they really doing there? This expense is not justified by the research claimed of dubious value. These are not tests or experiments, they are permanent facilities that collect and transmit data for unknown purposes. There are top secret activities in Antarctica that huge corporations don’t want the American people and US Congress to know exist.
