Grand Prismatic Spring (left) and Excelsior Geyser (right). Grand Prismatic Spring displays a stunning rainbow of colors created by species of thermophilac (heat-loving) bacteria that thrive in narrow temperature ranges. The blue water in the center is too hot to support any bacterial life, while the outer orange rings are the coolest water. Grand Prismatic Spring is the largest spring in the United States and the third-largest in the world. Midway Geyser Basin.

The Tree of Eons, a spectacular dendritic formation in the Bentonite Hills of Utah. Fantastic colorful sedimentary patterns, ancient Bentonite layers are exposed through erosion in the Utah Badlands. The Bentonite Hills are composed of the Brushy Basin shale member of the Morrison Formation. This layer was formed during Jurassic times when mud, silt, fine sand, and volcanic ash were deposited in swamps and lakes. Photographed just before sunrise with soft pre-dawn illumination.

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.
