Humans have mapped every corner of the globe – from jungles and deserts to the depths of space. Yet we’ve gone only seven miles below the Earth’s surface – just one five hundredth of the way to the Core. The two-hour documentary JOURNEY TO THE EARTH’S CORE goes deeper: 4,000 miles down to the heart of our planet. Along the way, scientists, engineers, explorers and adventurers encounter an underground world where: strange life forms inhabit deadly environments over a mile down; trees force their way through 400 feet of rock to find water; 1500-foot tall skyscrapers are built on sand; mines are the size of cities; and prospectors give the Earth electric shocks to help find oil. It also a place where people run marathons, make parachute jumps and scuba divers edge their way to the base of the world’s deepest caves.
