The Man Who Moved the MountainsStreaming Video - 2005
The map of the Earth is a flat picture of the Earth's surface; this BBC Horizon program presents the story of how Harold Wellman changed that picture. Hired by the New Zealand Geological Survey to map the underlying bedrock of the Southern Alps region, he noticed that there were invariably only two kinds of rock, granite and schist. His search for the boundary between the two led to the discovery of the longest straight line on Earth and a radical new theory that describes the Earth's surface and permits geophysicists to explain how mountains are built, and why they are such a prominent feature of the landscape.
