Dryburn Cleugh is the groove immediately in the foreground of the image; Dryburn Moor lies beyond. The fencing to the right of the image centre surrounds an open shaft in the hill slope which angles down into the ground. In such a location, West Allendale in the North Pennines, it's tempting to think that there's a metal mining connection but the photographer is more inclined towards it being a naturally developed cavity.
