Snowdonia Winter Mountaineering

This weekend I've been in North Wales staying in Nant Peris just at the bottom of the Llanberis pass. With the snowfall across many parts of northern England on Friday morning we decided to pack our winter gear in case anything was in condition.

Lewis on the walk in.

We hitched up to Pen Y Pass on Saturday morning, kindly picked up by some member of RAF Leeming who were heading round to Ogwen. We walked in on the Pyg Track to Clogwyn y Garnedd to have a look at the Trinity Face. The visibility was low, by the time we got to the Glaslyn it was dropping from around 100m to less than 25m. We headed over and geared up not far from the ruins at the top of the Glasyn headwall. We then made our way up to the Spider snowfield at the base of the Trinity routes. While the turf where exposed was well frozen, the rock was well rimed and there was ice forming there was still quite a depth of unconsolidated powder, which is a lot of places has a substantial layer of windslab sitting on top of it.

Myself climbing a variation to the left of Left Hand Trinity.

The weather was bad with strong winds blowing snow around and causing continuous spindrift avalanches to flow down the gulleys. We started up Central Trinity II 2 and after a short distance reached the large chockstone which is not yet banked out so we passed it on the left via an ice smear. Shortly after this the weather intensified and the spindrift avalanches got bigger, this coupled with the fact that the wind loading the exit slopes above was worrying me a little so we decided it was prudent to bail. A short abseil overt the chockstone and we were able to downclimb/walk down the rest of the route back down into the Cwm.

We traversed round the Cwn before picking a interesting but easy and safe line to top out onto the ridge on, I manged to spot a few interesting mixed lines to play on as well to keep things interesting. The wind was pretty strong on top so we got our heads down and headed down the tourist path to Llanberis.
