In reply to jock.anderson:
There's been quite a bit more snow since the pic that PPP linked to. I was on Beinn a' Choin above Inversnaid yesterday and there was patchy cover, mostly soft and slowly thawing, down to 400m on southern slopes, more on the north and north-east. Narnain/Ime etc looked quite wintry, Lui very white. So maybe not a full-on taste of winter but certainly not summer.
