The Snake Den Ridge Trail ascending the crest of Snake Den Ridge in the Great Smoky Mountains National Park, in the southeastern United States. Tree at right side of trail is <i><a href="//commons.wikimedia.org/wiki/Pinus_pungens" title="Pinus pungens">Pinus pungens</a></i>, with <i><a href="//commons.wikimedia.org/wiki/Picea_rubens" title="Picea rubens">Picea rubens</a></i> foliage at the extreme right. The ridgetops are too narrow and the soil is often too acidic to support large wooded plants, paving the way for rhododendron thickets.
