Photo Of Airline Beacon / Arrow

The only beacons I've looked for are long gone, but I suppose some of them are still around and have been recovered and photographed by us intrepid benchmarkers.

And I don't really like the idea of having a cache close to one of the FAA's important pieces of property. Maybe out in the boonies no trouble will come of it, but it is not much different than airport perimeters if somebody official sees you there.

I have never seen an airway beacon, but I suspect they looked a lot like the airport beacon at HM0531.
The device in the 2oldfarts' photo, above, is a VOR/DME. Although no longer cutting-edge technology (having been surpassed by inertial and GPS systems), VORs and TACANs are still considered to be critical components of our national infrastructure, and are both aviation mission and aviation safety critical. I would steer more clear of these than I would railroad ROWs.

Artman was talking about the similar, but historic AIRWAY BEACONS, and their cousins, Concrete Arrows. They were similar to Airport Rotating Beacons, but were for long distance navigation (there were transcontinental routes!). Thay later had "AN" radio beacon stations [long story] and then then newer low frequency (near AM radio channels) radio "homing" beacons (non-directional beacons = NDB). [NDB's are still used as LOCAL airport aids, as part of ILS landing systems - different story]. These airway beacons ARTMAN asked about are seriously obsolete (50+ years?), and I doubt many (any?) survive where they used to be (maybe some were moved to aviation museums?). I have hunted for several in California, with no joy (as a pilot would say = didn't find). I think I have a pic of the wreckage of one on the top of a peak. I'll post it if I can find it. As I recall, it looked like it rusted to the point it fell over. 50+ years will do that with no maintenance, even in California!
BTW, as of 4 - 5 years ago, there were very large Concrete Arrows (lighted at night) that helped you make a relatively tight turn on approach to Kennedy International in NY! Talk about dinosaurs, but hey, whatever works!
Here is a link to some very serious historical information about Airway Beacons , including some pictures of arrows! I suspect at least some (most?) of these must have had surveyed locations, probably with associated "Benchmarks" (likely triangulation stations, not Bench Marks). Collision of two hobbies (Benchmarking & Airway Beacons). Interesting. Thanks, Artman!

THAT IS A GEOCIEVER.
MOST DO HAVE BENCHMARKS NEAR THEM...........................BUT
I WOULD FOLLOW THE DIRECTIONS POSTED.
