English: Hutton's Unconformity, Siccar Point
This spot is a mecca for geologists from all over the world. Here, James Hutton found the evidence to prove that the Earth was much older than previously thought. He realised that the junction between the vertical and horizontal rocks represented a gap in time of many millions of years, during which the lower rocks had been deformed and eroded before the upper layers were deposited on top.
