The San Andreas Fault marks the boundary between the Pacific Plate and the North American Plate. Just south of San Francisco, the fault is visible in the form of a long, north-south trench that has been filled with the waters of Crystal Springs Reservoir. In spite of the obvious danger, human beings continue to develop the land surrounding the fault. Bridges and freeway overpasses stand within a stone's throw of a moving continent, while a dam actually straddles both sides of the fault. It's difficult to imagine how these developments will be affected the next time the earth decides to move.
