Summary Author: Thomas McGuire

Over the past 20 plus years, the Earth Science Picture of the Day has
featured a number of arch formations. Shown above is the
Grosvenor Arch, south of Cannonville, Utah. It’s an unusual double
arch 150 feet (46 m) above the desert floor. The largest of the two has
a span of approximately 100 feet (30 m).

If the name Grosvenor sounds familiar, it’s because this arch was named
for Gilbert Hovey Grosvenor who was the president of the
National Geographic Society for 34 years (1920–1954). He was also a
founding proponent of our National Park System.

The arch is an iconic feature of human architecture, from bridges and
dams, to towering cathedrals. Building materials such as stone and
concrete have great compressional strength making them prime materials
for use in load-bearing arches. Structural arches can support
exceptionally heavy loads, and even cable-stayed suspension bridges
often take advantage of arches (inverted arches) to handle the
tremendous loads they support. Photo taken on March 26, 2007.
