Having had the opportunity to photograph some of the natural and man-made arches that dot the landscape of our nation, I decided to show just a few.
A natural arch is a rock formation that forms after many years of continual erosion. Many natural arches have been designated historical sites or national treasures and are protected by government regulation. Arches National Park near Moab, Utah is one example.
Man-made arches come in a variety of types. Some man-made arches have been documented to have been built as early as the Bronze Age dating to 1850 B.C. Bridges, entrances, and tunnels are just a sampling of the uses of man-made arches.
