The rope  on the sump bypass in Ogof Pasg is looking pretty tatty.  There is a knot about 3m off the ground where it looks like
someone has mended a dodgy bit. It doesn't look too clever just below the knot either.  I don't think the knot would be obvious
from above.  So if anyone is going there don't expect to find a sensible rope.

I don't know whose rope it is ; I don't think it is particularly old.  I didn't remove it - I was coming from Ogof Foel Fawr and 
didn't go back to the anchor after going through the sump. The sump is just open with a couple of inches airspace so is really a (very short) duck.  I imagine the water level is falling.
