The bridge gives easy access to the stream bed. The base of the Almscliff Grit crosses the stream about too m below the bridge, but is not well exposed. The beds below the grit can be seen in the sections on both sides of the bridge. They are dark grey argillaceous siltstones with a great variety of paler-coloured sandstone interbeds, ranging from a few millimetres to over a metre in thickness. Some of the sandstone beds are graded, with '''sole structures''', and are probably turbidites. All suggest rapid deposition on a delta slope fed from the mouth of a large river. Instability of these deposits, giving a tendency to collapse under their own weight, is likely to have caused the slump-faulting observed at Almscliff Crag.

Follow the path, which climbs up the east bank of the stream to the lip of Oakdale and along a ridge marking the outcrop of the Almscliff Grit.
