The method is still a standard for cemetery studies.
The scholar most associated with the rules of stratigraphy (or law of superposition) is probably the geologist Charles Lyell.
The basis for stratigraphy seems quite intuitive today, but its applications were no less than earth-shattering to archaeological theory.
In 1929, they found a charred log near Show Low, Arizona, that connected the two patterns.
It was now possible to assign a calendar date to archaeological sites in the American southwest for over 1000 years.
