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.

The Botanical Building in Balboa Park, San Diego. The Botanical Building, at 250 feet long by 75 feet wide and 60 feet tall, was the largest wood lath structure in the world when it was built in 1915 for the Panama-California Exposition. The Botanical Building, located on the Prado, west of the Museum of Art, contains about 2,100 permanent tropical plants along with changing seasonal flowers. The Lily Pond, just south of the Botanical Building, is an eloquent example of the use of reflecting pools to enhance architecture. The 193' by 43' foot pond and smaller companion pool were originally referred to as Las Lagunas de las Flores (The Lakes of the Flowers) and were designed as aquatic gardens. The pools contain exotic water lilies and lotus which bloom spring through fall.
