Description
Finely executed geological lithograph map of the Midwest and contiguous regions, published by American geologist James Hall.
The map is color coded by 23 geological formations for which there is a key in the lower right.
Hall’s map is one of the earliest known maps to employ the “New York System,” of stratigraphic nomenclature developed by members of the New York Geological Survey. The system emphasized the importance of paleontology for illustrating geological units and introduced the concept of "type locality," a primary reference location used for defining the characteristics of geological formations.
