A specific one you can't think of the name? Or any one so you can climb while in the area? The nearest significant crag is probably Trowbarrow (that is if you don't count Fairy Steps, which I wouldn't).
In reply to Rog Wilko: I'm thinking it probably Warton. It looked OK climbing in the afternoon sun.
No, on checking the map it's not Warton, nor in the UKC database, or my old Lancs guide.
Nothing new - local climbers have known about this crag for years. Despite being 20m tall and poking well above the trees it seems to have escaped guidebook attention. Two of the best climbs are 'April Showers' and 'Fool on the Hill' apparently. I can't comment myself as I've never been able to to find the approach that bypasses the Dallam gamekeeper's lodge.
