We went back to Cwm Silyn today, and wanted to try the route next to Mask of Death (yesterday) which was a nice looking ice route called Bedrock Gully IV,4. However after walking to view the base of the crag, in the 70mph gusts we decided against it. A lot of snow has been blown about all night and probably much of today. Picture of banked up snow behind the wall. There is definitely layers in the snow and most probably some wind slab being formed on North Westerly aspects. So be cautious tomorrow.
