In reply to windjammer:
Calf Cove on the south side of Great End gets quite a big snow build up. This is the small cove that the path goes through on the way from Esk Hause to Scafell Pike. Ultimately it all depends on snow deposition which in turn depends on wind direction so things can vary from year to year. So long as you keep away from avalanche slopes and chutes you should be OK.
In general, you need to be looking for a small outcrop or short steep slope that is in the lee of the prevailing wind so that you get a short deep bank of snow.
