Brilliant info, ced2 - I mistook Ingleborough for Pen-y-Ghent. From some angles they are certainly similar. So, if we are looking at Park Fell, Simon Fell and Ingleborough on the left we must be near Ribblehead station. I was wonderining if any filming was done around there and was going to ask the landlord or staff of the Station Inn, when we next go.

You are quite right about most of it not being at Ribblehead - It is, in the main filmed around Huddersfield and Jericho itself was built in an old quary in the same area.
