If that's the tarn below Seat Sandal, you've gone to a lot of trouble moving Gable and the Scafells to somewhere in the region of Penrith.
You're sort of on the right track. What's the Tarn called and where am I standing?
(Rearranges mental hills strenuously, swapping Fairfield and Seat Sandal back into possibly correct positions....)
Grisedale Tarn, and you are at Deepdale Hause.
If that's wrong, I'm even more confused.
If it's right, please can someone else post the next one, I can't at the moment.
