Went hunting for this because the Nazis have decided that white crosses in the desert are secret signs of a clinton-mexico pedophile sex ring. I was very disappointed that they hadn't fixated on the Corona Landmarks because that would have been awesome.
Somewhere up in here we've discussed the Corona Landmarks before but I can't find it. I'll bet it's some lame Atlas Obscura thing.
I saw that article about the Amerinazis, too, and was laughing my ass off... it's like they don't know how to use Google, or something. There's an entire subculture of people who - long before geocaching was a thing - would go out and photograph these old landmarks, and the ones from the Transcontinental Air Mail Routes, that are still around. I've even been to the one in WA!
