Pioneers of Appalachian/Caledonian Geology
To ensure our commitment to the heritage of Appalachian/Caledonian geology, the International Appalachian Trail has established a chronicle of geoscience investigators who over many decades of mapping and research contributed to the development of the theory of Plate Tectonics and successfully applied it to the Appalachian/Caledonian terranes, thereby establishing the foundation for the IAT.
Introduction to Appalachian/Caledonian Geology
The Ancient Orogeny as Ambassador of the Geosciences to Modern Societies
Throughout human history, the geological foundation of our landscape has determined the location of settlements, trade routes, and human migratory paths, inextricably linking our culture to geology. For the past two decades, the International Appalachian Trail (IAT) has recognized our common geoheritage across the North Atlantic conjugate margins by establishing a long distance walking trail that extends beyond borders to all geographic regions once connected by the Appalachian/Caledonian orogen, formed more than 400 million years ago on the super-continent Pangea.
Now a committee of IAT geologists including Walter Anderson, Robert Marvinney, Jim Hibbard, John Calder, and Hugh Barron have established guidelines and selected the first group of deceased honorees who are being recognized for their significant contribution to the understanding of Appalachian/Caledonian geology.
