There is a show on the Science TV channel called, "What on Earth". The show depicts satellite images of strange geological occurrences and man-made structures on Earth. About a month ago they had a complete show regarding the concrete airmail arrows. If I remember correctly, they showed arrows in 3 different states, all out west. Very interesting.

Yes, this is quite an interesting aside to the early airmail days in the US.

I'll be including more of this info in the update to my article about the US Scott C11

Beacon airmail stamp of 1928.


I hope to someday take a trek across the USA to visit the last known remaining ones.

There are many of the arrows still out there, and also a couple restored towers!
