Without checking the maps I'm only certain about one of these.

a) Leg 3 - Great Rock - obviously! Just before crossing Staups Moor down to the bridge before the road climb to Blackshaw Head.

Isn't this the place of local legend where they say the devil jumped from Stoodley Pike to Great Rock and you can still see the imprint of a cloven hoof in the top of the rock where the devil landed?

And the rock is covered in carved graffiti, some of it very old.

f) Leg 2 I think but not certain - looks like the part of leg 2 descending into Todmorden down the twisty road past the church.
