Shenandoah National Park Things to Do: 112 reviews and 322 photos
There are numerous rock formations along Skyline Drive, in upper parts of Blue Ridge Mountains. I've seen a few but they were not very interesting by size and shape. Well, nothing compare to rock formations of northern Arizona and Utah I was lucky to see a year before.
Most of the rocks in Shenandoah National Park are covered by beautiful greenish-white or white plants, probably lichens which are the first colonists on exposed rocks. Later on I've got to know that 69 species of lichen are known from Shenandoah National Park. Two of these species, map lichen (Rhizocarpon geographicum), and black crust (Melinelia stigia) are extremely rare in Virginia and found only on rock outcrops in the central district of the park. Are they on my pictures?
Lichens are a specific group of fungi unique because of their symbiotic relationship with green algae. The algae provide carbohydrates from photosynthesis to the fungus, while the fungus provides nutrients from decomposition to the algae.
