| Zusammenfassung |
| William Maclure's pioneering geologic map of the eastern United
States, published first in 1809 with Observations on the Geology of the United States, provided a foundation for many later
maps – a template from which geologists could extend their mapping westward
from the Appalachians. Edwin James, botanist, geologist and surgeon for the
1819/1820 United States Army western exploring expedition under Major
Stephen H. Long, published a full account of this expedition with map and
geologic sections in 1822–1823. In this he extended Maclure's geology
across the Mississippi Valley to the Colorado Rockies. John Howard Hinton
(1791–1873) published his widely read text: The History and Topography of the United States in 1832, which included a
compilations of Maclure's and James' work in a colored geologic map and
vertical sections. All three men were to some degree confounded in their
attempts to employ Wernerian rock classification in their mapping and
interpretations of geologic history, a common problem in the early 19th
Century prior to the demise of Neptunist theory and advent of
biostratigraphic techniques of correlation. However, they provided a
foundation for the later, more refined mapping and geologic interpretation
of the eastern United States. |
