About Siccar Point
In 1961, Siccar Point attained Site of Special Scientific Interest Status, based the location's influence on James Hutton's 1788 Unconformity theory. At Siccar Point, nearly vertical sedimentary rocks of Silurian age - greywacke sandstones and mudstones - are covered uncomfortably by a younger sequence of red sandstone and breccia. This showed that Planet Earth is much older than was taught in the Bible. A casting of the Siccar Point unconformity is housed in the American Museum of Natural History.
