I was climbing at Round Barn Quarry and I saw a finger crack to the left of the cave mouth below Scarey Buttress. I climbed it (pleasant enough) but couldn't identify the route in the guide book (Lancashire Rock) and the routes on here are lacking descriptions in most cases. I did wonder if it was Thundercrap (S 4a) but in Lancashire rock that was described as the left side of a pinnacle and this appeared to be on the pinnacles right.
The line is the obvious crack taken direct where it flares out towards the top in the image below.
In reply to Rupunnini:
Thundercrap:
The obvious jamming crack two metres left of the recently-formed corner groove on the left of the cave. A top-rope may be advisable?
