GeoPicture of the Week: Geologic Faults

This picture from Cornell University really encapsulates the beauty of a geologic fault – it’s like someone took it from a text book and slammed into real life. In geology, a fault is a planar fracture or discontinuity in a volume of rock, across which there has been significant displacement along the fractures. You can see how the different layers (strata) of rock moved relative to each other.
