The Air Mail route from New York to San Francisco with beacon locations.
A model of one of the arrows and beacons at the IPMS (International Plastic Modelers Socity) Nationals contest in Loveland, CO, which you a pretty good idea of the layout. Photo via here.
There is also this fully restored restored tower and its generator shack in New Mexico.
While no one bothered to remove the concrete arrows, many have probably been caught up by development but an outline could still be visible from the air if they were just covered over by a grass lawn. Or maybe you might just come across some concrete remains that seem very out of place in the middle of a field…
Anyone feel like getting lost on purpose to go on a treasure hunt for these giant arrows to the past?!
