The LDMT went around that area a few years back (2018?). I recall running along the side of Coledale Tarn at one point.

That whole area east of High Raise/Sargeant Man,and west of Easedale Tarn/Tarn Crag, seems confusing and a number of paths/trods which aren't on maps.

Doing my final Wainwright last year, attempted a direct route from the head of Wythburn valley across to Pavey Ark, and found it very challenging in zero visibility.
