Pre-Dawn over the Tree of Eons, Utah. The Tree of Eons is a spectacular geologic sight near the San Rafael Swell. Erosion has cut a "tree" through red, blue, purple and white layers of the Chinle formation. The Tree of Eons is a superb example of dendritic erosion and to really appreciate the complex fractal-like details it must be observed from above. Photographed here in the soft, predawn light, it takes on magenta, red and purple hues just before the sun reaches it. Aerial panoramic photograph.
