Medicine Bow Aiport (Site 32 SL-O (Salt Lake-Omaha) Intermediate Field Historic District).
Teletype hut and beacon tower.
I didn't know that Medicine Bow had an airfield at all until MKTH photographed it. I've never been to it myself.
But it does, as these photos show.
As these photos show, not only is a strip still there, but one of the big concrete arrows (which I've never seen in person myself either) is on the strip, indicating that it was once part of the Transcontinental Air Mail system. It must have been part of a connection between Cheyenne and points further west, but what the next western airfield was, I don't know. My guess would be Rawlins, but that would be just a guess. According to the submitting material for its placement on the National Register of Historic Places, it was an emergency field on "Route T". This was "Site 32" on the route.
