A line from a center rock, over a specific boundary rock, intersects the feature called Bears Den Rocks on the mountain. Standing on that center rock, looking northeast, a viewer can see the sun rise over Bears Den on the day of the summer solstice in June.
Moving around the circle, another set of rocks points to Eagle Rock on the Blue Ridge, and also to sunrise on the day of the spring and fall equinox in March and September.
Yet a third points to a saddle in the mountain, where the sun rises at the winter solstice in December.The "mountain" being referred to in the above excerpt is the Blue Ridge.
Astronomical alignments have been found (or least have been claimed to be found) in a variety of Native American sites, including Mound Builder sites such as Serpent Mound and Anasazi sites such as Chimney Rock. Another site known for such alignments is America's Stonehenge in New Hampshire, which is also called Mystery Hill. Read the full story at the above newsleader link.
