Just posting this to show my three readers (Hi, mom!) that I’m actively running through every thread that might lead to info on the AZ Concrete Crosses. US Geological Survey would have used any photogrammetry range available to the US government during mapping actions in the 1960s and 1970s. So if anything exists and gets found, I will post it here.
This FOIA request was worded specifically to call out any usage of the range. If I had used “Arizona CORONA Calibration Crosses,” the request would have been stored with the UFO-related ones… in the “round file” (trash can).
(Oh BTW, my oven is warming up to bake some Humble Pie, if need be. I’m man enough to admit I’m wrong, if that’s the case and evidence *actually* exists. But I don’t think so…)
