  • Geology of the Smokies i THE geologist will find in the Great Smoky Mountains National Park a wonderful field for research. Extracts from an article published in the Journal of the Tennessee Academy of Science, written by L. C. Glenn, professor of geology at Vanderbilt University, are interesting: "The rocks of the region embraced within the Park are of varied character and age. They include limestones, shales, slates, sandstones, quartzites, conglomerates, gneisses, schists, and perhaps some granites along their eastern border in North Carolina. "The youngest of them belong to the Mississippian, and yet are many million years in age. From these younger ones they range back through the Devonian, Silurian, Ordovician, and Cambrian to the Archean. The latter are many, many million years old—so old, in fact, that they are probably among the earliest formed rocks on the globe, and have had their age estimated at some hundreds of millions of years. "North of Little River there are some Silurian and Ordovician rocks along the west base of the Chilhowee Mountains, while in Miller, Cade, Tuckaleechee, and West Coves there are large areas of Knox dolomite of Cambrian and Ordovician age. This dolomite is less resistant to erosion—and especially to solution—than any of the surrounding rocks so that after long ages of weathering it forms depressed areas, known as coves. These coves have a much better soil than the rougher areas about them and contain the best farms of the region, in fact, they constitute almost the only good farming lands within the proposed park. The only other lands to be classed with them in this respect are the narrow flood plains found along some of the larger streams. "On the high crests along the state line, weathering has here and there produced great gently rounded ridges or domes that have accumulated a fairly good soil cover and that are practically, or quite, bare of trees. They are grass-covered and form attractive parklike areas known as balds. "Included in the gneisses are here and there areas of ancient igneous rocks that have been forced up into the overlying gneissose rocks, which may have themselves also been originally igneous. The metamorphism has been so intense that much of the original character of these rocks has been lost. We know that they are very, very old and group them together under the term Archean, the age that includes the oldest known rocks. "The geology is such as to fit the country best for preservation for its scenic beauty in a great national park."
