Summary
This example correlates formations throughout a large region in the southwestern part of the United States noted for its spectacular scenery. The composite section can be thought of as representing a large, although incomplete, segment of relative geologic time. A global time scale has been derived by extending the correlations from one place to another and reaching from one continent to another. These correlations are based in large part on fossil evidence.
