In reply to Northern Mountain Monkey:
I think the head of Langdale often gets more snow than Gable or Scafell as it's dumped on the crag having been blown over the Bowfell ridge. Also the routes are generally steeper than the Helvellyn ones so the turf isn't insulated as much. There are also a number of crag aspects from North facing through to almost South East, so often something has come in whatever direction the weather has come from. And it's also, (for the lakes,) pretty high.
I've had a number of 'we'll go and have a look' trips up there over the last few years,(this one included,) and come away with some good routes climbed.
