In reply to scottidog: The Wiltons generally face North East with the exception of the inside of the prow which ain't great as the wind is coming from that direction. That said, I haven't been down to see what snow is there.
Neither have I been to Brownstones but have seen pictures in recent days on here of snowdrifts at the top of most walls and melt water seeping onto the rock. Obscenity Wall is clear I think though.
Anglezarke is completely free of snow where it matters, and the walls are almost bone dry thanks to this prolonged spell of good weather.
