Dave, Neil and I went into Cwm Cneifion today. Paths are now ok so wasn't too hard going to get in there. We decided to have a crack at Left Hand in the end. There was plenty of activity round the Cwm with teams on Tower Slabs, El Mancho, Right and Left Hand. The first pitch was thin but took a few stubby screws here and there, gear was a bit sparse (probably got a V). Last main pitch was expansive, ice was pretty brittle, but pleasant sustained III. Top out was baltic, bit of breeze, major windchill, frozen water bottles, etc. Beautiful walk back, sunset then moon rise. Going to have a look at the back of Idwal in the morning, sounds like the Screen may be ok again.
