Modern maps collectively call these slopes 'Woolholes' but it is Crossing who first mentions it, in passing, as two separately named areas; "Keeping near the boundary hedge L. he will pass above the two clatters that stream down into the river, known as Woolholes and Higher Woolholes, in which Reynard sometimes finds a shelter."
It is Hemery who gives a better clue as to the actual locations; "The west foot of Dockwell Ridge is Woolholes Plain, on which lie Woolholes Clitter and Higher Woolholes Clitter... An old enclosure-wall, much overgrown, runs up the hillside from the rocks of Higher Woolholes Clitter, turns southward and drops to the valley floor opposite Brent Moor House."
This is the lower "clatter" on Woolholes Plain. Whilst it is considered clitter, there are a couple of significant piles to warrant a visit, including the one that is closest to the bridge which houses a small cave/shelter shown in the last photo. The area is overgrown with bracken and the majority of the rocks are hidden beneath your feet so tread carefully when bagging both this and Higher Woolholes.
