A hike through Kentucky’s Red River Gorge is a trip that outdoor enthusiasts never forget. The adventure begins amid rugged terrain with towering sandstone cliffs that contour steep, forested slopes. Visitors discover hundreds of natural stone arches and other unique rock features that create some of the most splendid geological formations east of the Rocky Mountains. Within the beauty and solitude of the gorge resides a rare plant found nowhere else in the world.
The white-haired goldenrod occurs predominantly in the Daniel Boone National Forest, typically found growing along the base of cliffs or on ledges. In areas where the ground is undisturbed, this plant thrives in moist, sandy soil underneath rock shelters. During the fall, the plant blooms with bright yellow flowers along its upper stem. Alternating white-haired leaves line the stem from its base.
