The gorge has over 225 species of wildflowers, plants and trees, with scattered stands of old growth forest on some of its steepest walls. The rest of the gorge is covered with thriving second growth forest that can be over one hundred years old. Since clearcutting, nearly 90 percent of the forest land has burnt at least once. Typical south-facing slopes here have mountain laurel below oak and hickory trees, while north-facing slopes tend to have ferns below hemlocks and hardwoods. Large chestnuts and black cherry can also be found.
