A local real estate agency has some nice photos on their website. Both parcels are in Bovina, NY. The links will take you to their slide shows.
In this first one, look closely at picture #5 and, if I'm not mistaken, it looks like there are two cairns on top of the outcrop, just off to the right. Then picture #6 is a stone wall attached to an outcrop.

In the second one, the first picture looks like it could be a platform pile. The fourth picture is simply stunning. I have to chuckle to myself about the Realtors comments: "Some selective cutting could produce some long range views" and "Distant Mountain View" at picture #2. No surprises there!
