The photo might be from the other side with the creek in the foreground -- the stone wall might be on the edge of the rocks in the crek. The ground pattern doesn't exactly match but it's hard to tell with thick forest in the photo and just a few trees now. The roofline and window patterns seem like a close match.

Can anyone make out the rest?

Also known in western Pennsylvania as a 'Frost Wall,' will shift and move with the freeze thaw cycles of winter. That's a beauty of stone fence there.

Looks like a great place to practice your summertime porch sitting !

That dry fit stone wall is a work of art. It reminds me of a favorite children's book, "Matthew Wheelock's Wall," that chronicles the building and graceful endurance of a northeastern farmer's stone fencerow. It is a beautiful allegory about craftsmanship and mutual support. I think some remaining stone fencerows in the U.S. are preserved as historical and cultural sites, as many are in Great Britain.
