On our last day in Ulster County, NY a couple of weeks ago, we went for a walk in an area of mixed stone features. Unfortunately, unbeknownst to me, my camera was on its last expedition, and the quality of the pictures leaves something to be desired. The picture above shows a Conservation Corps spring box we found along the trail We'd heard it was there and we had no trouble identifying it.
Above is an ambiguous feature that could well be colonial or later. I'm not sure what it was, but thought it worth photographing especially because of the metal item laid on top.
The picture above shows one end of a wall that came up a steep bank from the stream. We'd seen some walls that were definitely agricultural in the area, very squared off and somehow unmistakably farmers' walls, but this had a different look and was associated with a spring and some much more freeform structures that didn't photograph well. It's possible this was ceremonial.

Here another interesting wall ranges uphill.
This very small pile along the path added to the mix of stone features. On a short walk we saw agricultural walls, the CC spring box, this and another very modern pile, and some possible ceremonial structures. The styles were distinct, all using the same material.
