In 📷 2 North (the top of the map) is approximately aligned with the red North needle on the compass
The map and the ground are therefore orientated the same way - the map is “set”

I was 🤔 for a bit, as initially I thought we were pitched on Horse Stone.
However I think we are looking W to the local high point on Barrow stones, from just NW of Crow Stones, with the white box being 🐎 🪨
Then follow features round the Derwent

Not too confident with this one. Map doesn’t seem to show the meanders marked SE of the 🟨
Also the number of interlocking spurs doesn’t quite fit…..
Will await tonight’s solution

We are at the head of stream draining W from Bankstop Hey (?fence post from the FB below us)
I thought the 🌲 in the Westend valley was crag at first 🤦🏼♂️
In front of us is a hook shaped spur between the Westend and Blackclough. The points lie either side of this on steep gullies

Looking N from Merklin Park
This is the only wooded flat bottomed valley. Also it’s the only spot with a concave slope in the right place relative to the water
