When was the last time you pulled out a map for directions?
Think about how difficult it was for people hundreds of years ago to travel without GPS systems…Believe it or not, back then, all you had to do was follow the giant arrows that pointed you in the right direction.
70-feet concrete arrows are scattered across the country. Follow them and they’ll lead you out of the desert.
They were created by the US Postal Service’s Air Force and will lead you across the continental United States.
Constructed in 1924, they were used to guide postal planes in the right direction as they carried mail from coast to coast.
The first generation of planes lacked radio technology, so they used arrows instead of towers to navigate.
The arrows and beacons bisect the United States from San Francisco to New York City.
The towers were 50 feet tall and fixed with gas lights so that they could be spotted from miles away. This model represents a beacon and arrow in its heyday.
World War II brought a major advancement in radio technology that rendered the arrow system obsolete.
There has been an effort to preserve the historical beacons and arrows, like this one in New Mexico.
