A number of Archaeologists have directed me to the aerial photos at the University of New Mexico and the BLM. Any trails visible on old photos would predate ATVs and WW2 jeeps. It is the most valuable resource I could have.
But, it was one of those things I never got around to. Finally, last year, I contacted the local BLM office and they have a set. The photos are from 1936, have impressive resolution and appear to be from 10,000 feet or so altitude. The nice lady at the BLM is very protective of the pictures. She held my camera and Land Rover hostage long enough for me to take one of the photos home to scan.
At first I did not see much in the image. It is from very high altitude. The topography is confusing. Trails are not distinct from drainages. There is little obvious enough to jump out at you.
After six months of 'off and on' examination I got an idea. The pictures are only 70 years old. The trees are at least that old. So, unique tree patterns should match images from Google Earth. I blew up the image until it almost pixelates and moved around until I found what looked like a circle of trees. Then went to Google Earth and searched the same area - Shazam, there were the trees. That gave me an exact reference point on the photo. I pulled in a photoshop blue line and scrolled down it until I came to a feature. Right there was a perfectly straight trail that I had never noticed. I did the same thing on the Google image and there it was - a familiar feature that I have always assumed is a county drainage ditch. But, it was there in 1936! Why would the county dig a drainage ditch on top of a mesa in 1936. Could have been the CCCs. It also could have been an original trail. It's a starting point.
So, that's what this thread iis about. We are making a lot of discoveries based on the photo. I'll detail the method and results here. The original photo is below. Will attach higher resolution scans of sections as we progress.
