In reply to Lewis Robinson:
As a purveyor of north west grit, having climbed in most holes in the grounds, I'm going to stick my neck out and say probably not. Even the perma-dry quarries that you can often rely on have started to seep now. It is meant to clear up tomorrow around lunch time but it'll be dark before anything's properly dried. Then Sunday it's due to rain again.
Of course if you were absolutely desperate then I'd head for New Mills as a first port of call, it doesn't seep too much there but it can feel greasy and if they grass is wet at the base then it'll feel pretty rubbish anyway. As a secondary then Greetland quarry is also reasonably reliable but was beginning to seep earlier this week and we've had more rain now.
