In the Black Mountain range in Yancy County stand six of the tallest peaks east of the Rocky Mountains. All exceed 6,500 feet. The tallest is Mt. Mitchell, at 6,684 feet, which is also the tallest in eastern North America. Named for its early explorer, Elisha Mitchell, the peak is a place of great beauty and weather extremes. Currently the mountain's Fraser firs are dying from an imported European pest and acid rain and fog. Development is slowly creeping in upon the mountain, also.
