The geologic features seen in Virginia are as varied as any in the country. Indeed, in 1985 the highway east of Natural Bridge was identified as the most geologically interesting 24 kilometers of roadway in the southeastern United States and one of the four most interesting in the country. In addition to Natural Bridge, you can see caverns still developing their unique architecture, geologic structures developed at the end of the Paleozoic era, fossils of Paleozoic life, preserved beaches from late Precambrian shores, and more, all in a single stretch of highway.
