Were off up there again this weekend.
At Low Snab cottage, if you walk on a few hundred metres instead of turning right for the hill, you come to the entrance of the abandoned Goldscope mine. It entrance is open and it's common to wander up it, for close to 200m with a torch. You then come to a bit too low for me to want to try!
On scope beck, just down from High crags, you see a small tarn. It's man-made with a dam. It's purpose was to run a man made stream (called a Leat) along the hillside back to Goldscope, then it went inside the hill to drive a waterwheel pump for the mine.
I'm not a person who goes potholeing or mining, but exploring these bits of the area adds a great bit of interest for me and helps me force myself to get out on bad days.
East of your start point, towards catbells (We did this before Christmas), you come across the abandoned Yewthwaite mines. Again, great area to explore for 1/2 an hour and mull over the amount of work they did 100's of years ago without machinery.
