Geograph - photograph every grid square

Looking down over pasture to the outlying farms of Hartley, from the parapet of Merrygill viaduct (now owned by the Northern Viaduct Trust). Hartley Beck is the stream crossed and this flows among the trees to the right of the photo, on its way down to the River Eden through rich farmland. Having been bothered by the RAF earlier in the day, persistently flying noisy circles over the Warcop training area, we were treated to a much smaller flying display here, as a young man was piloting a small drone taking aerial footage over the viaduct. His approach to safety was admirable, with lots of warning signs so that we weren't surprised by the remotely operated aircraft.
