In reply to AlH:
OK fair enough. When I did tower ridge around feburary some years back there was several feet (or more) of good neve over much of the ridge covered with 6 inches to a foot of powder. There was ice all over the shop and quite a lot of largish icicles around and about. There certainly wasn't anything melting!
My memory of ledge route is that the majority of it is really a kind of series of shallow gullies and to be in good nick these will be hard neve of quite some depth, certainly wouldn't be expecting to see partially snow covered rocks here.
Anyway I wasn't trying to take anything away from the ascents good on you all I'm clearly jealous. I'm not in anyway saying that I wouldn't have been there cllimbing too if I could have been. However I think you'll agree that typical good mid season conditions (which is what I would call full winter perhaps with some hardcore weather thrown in) would be quite different to what was experienced during less than 1 week of wintry conditions in early autumn last month!
I would say your blog is slightly disparate to your above description, your blog clearly says that the snow on the ridge was wet and mentions thawing ice/snow being problematic until the eastern traverse, also that 1cm of ice was present on steep windward rock rather than cladding everything. Also there was some mention of occasional black/wet rock.
