Maybe it is maybe it isn’t, I’m not sure.
We went to Blackstone Edge trig pillar today but failed miserably. To be truthful I was a little wary about setting off up the hill with it shrouded in mist but we got there. We looked around all sides of the pillar but couldn’t find any rocks that looked promising. In fact we couldn’t really find a place where the photo may have been taken from. We found places where the pillar in the background looked right(ish) but the rocks in the foreground didn’t look right. We found places where the rocks in the foreground looked reasonable but the pillar in the background looked wrong. The walk was pleasant albeit a bit muddy and once the mist had cleared the view was stunning. I can’t see us trailing up there again without it being a lot drier under foot.
This is the pillar itself
Trying to match up the view of the pillar with the clue picture
And again, trying to match things up. This particular direction was the only one that resembled the pillar part of the clue picture in any way.
