Large concrete arrows can be found dotting various landscapes across the state of Utah, but what are they for?
Devon Dewey explains how these arrows were essential for early aviators, and why the US government destroyed most of them just a few years after they were constructed.
“Back in the 1920s, the U.S. government built hundreds of large, concrete arrows across the country. The purpose of the arrows was to provide guidance for pilots who were pioneering the country’s airmail system.”
