I plugged in an old stick and it had several jobs on it. The site where these were taken was a "boulderfield" covered with the rocks you see Ed laying. The clients wanted a daylight basement, 3 sides underground. Seeing the rocks all I could say is "We'll try, I don't have a good feeling". We didn't hit a rock underground. It was the sandstone beach sitting on top of the uplifted mountain and that capstone, broken up just remained as the softer soil beneath it eroded away,
We also collected the farm field piles and scraped the surface rocks into a pile after I cleared the site and sawed the oaks into timbers and lumber.
A rubblestone wall, look in chapter 4 of the IRC for the rules is 16" thick. Ashlar (coursed) stone can be thinner. This is probably the technique I've used the most. There is a temporary back form, we establish the front plane of the wall and lay that with tapes, strings, straightedges whatever it takes to respect the line. It is slower than slipform but looks much better. I have a mixing pan full of mortar and a wheelbarrow full of loose, flowable concrete. Lay the face stones in mortar and backfill behind the face stones to the form with smaller chunks and reject rocks and concrete. I do try to get some rebar in the wall vertical and horizontal. This is far and away the tallest one I've had done. I've done several under houses in the 2-3' tall range.
