Hey sdcfia, I haven't left quite yet, and I hope you know I will joke around as you do , no hard feelings. I will report on the starlink, in fact I will try and post from it, in a week or so. We camp in a narrow canyon so it should be a good test of a hard spot for service. Usually we use the globalstar sat phones there which are intermittent at best and no texting , internet, etc, just a crummy phone, but nice for emergencies when you can get service, which is like a 2-5 min call every 15-30 mins.
There was too much stuff to look at in Arizona around the summer solstice, mornings and afternoons, I would love to go back , was trying to stay on my side of the road ....
I know in your picture there is a cliffside hoyo to peek thru on upper right of where you circled, sometimes these show a spot on the ground, but you would likely look for an entrance slightly further down the hillside from where the spot on the ground is and it would be tunneled. They liked to tunnel under an outcrop or cliff, as they were used to mining into mineralized spots which are mostly on the bottom sides of outcrops.
For the most part when you see a profile of something they were meaning to draw you closer to the area for either a window/peephole to an across canyon spot or an actual spot they marking somewhere on the hillside.
