Or, “The beacons are lit! Gondor calls for aid!”
Recently the Internet has become aware of a string of giant concrete arrows dotting the landscape across the country. Rumors abounded, with the Von Daniken crowd hauling out their tinfoil hats and other, more pragmatic folks doing more scholarly research. It turns out they were guideposts for our earliest courageous airmail couriers, who often flew in abominable weather, at night, in the dark, wet, lonely, and miserable. (How’s that for evocative prose. Thank you! Thank you!)
You can read a comprehensive writeup at Core77, and see some local Utah interest at KSL. I’ll have to get a picture of my own one of these days.
