The Blue Ridge is the highest part of the southern Appalachians, a range of forested peaks and coves with oak, hickory, tulip poplar and hemlock and spruce-fir on the summits, in one of the wettest climates in the East. Steep mountain streams drop over granite, gneiss and quartzite ledges, giving the region hundreds of waterfalls.
