There are a couple of other slate closeheads below "Rydal Cave" - just off the main path and very obvious. Bit of a scramble up in to them though. Nothing flooded. A very small working further along Loughrigg Terrace towards Grasmere. Again, not flooded. If you want a flooded slate working audit, there is one up Scandale in Rough Sides wood. Not really worth the steep climb up though.
