Photographer's Note

Earth's grandest temples were not built by man, but by Nature.
Millions of years ago warm shallow seas, or swamps, or sand dunes resided in varying places where today exists the Grand Canyon. Before that there is even ancient lava at the lowest level, 2 billion year old Vishnu Schist. About 65 million years ago the Earth's continental drift and colliding plates caused uplift which increased the stream gradient of the major river - the Colorado and its tributaries, which in turn increased the erosion speed and capabilities to cut through rock. Later the Ice Ages increased the amount of water in the Colorado River drainage system, which increased the cutting and deepness of the evolving canyon. The terraced walls and varying rock formations were created by 'differential erosion'.

This view is from near "Desert View" at the Grand Canyon's South Rim not far and east of the Visitor Center.
