The dramatic coastal exposure of the Carboniferous (also known as Coal Age) rocks, known as the Joggins Fossil Cliffs, are continually hewn and freshly exposed by the actions of the tides in the Cumberland Basin. Geologists were first attracted to this locality in the late 1820s with Abraham Gesner, Richard Brown, Thomas Jackson and Francis Alger all making important observations. A little later, a party from Williams College, Massachusetts became the first student party to study Joggins for educational reasons in 1835. However, the true fame of Joggins dates to the mid-nineteenth century and the visits in 1842 and 1852 by Charles Lyell, the founder of modern geology and author of "Principles of Geology". In his "Elements of Geology" (1871), Lyell proclaimed the Joggins exposure of Coal Age rocks and fossils to be "the finest example in the world".
