After completing the drone survey at James Yates Well, there was still 5 minutes flight time left on the drone so I decided to run a quick flight over the ruins near Rushy Brow. Just managed to video the approach, take a dozen overhead shots from different angles, which was just enough to produce a Digital Elevation Model.
Fig1: Orthometric image
An orthometric image was produced to take measurements.
There is a pile of stones there that at first glance look like a cairn, but the orthometric image shows a rectangular spread 6m by 4m. There also appears to be a ditch a few meters to the north.
Taking a ‘slice’ out of the 3D model (north to south) you can see the profile of the ditch and the height of the pile of stones (see Fig2).

Conclusions
This site was probably a building, maybe a Shooting Hut or a Sheep Fold. There are no signs on the detailed overhead shots of roofing material.
