The walk up was nice. When we got close we saw a white Landrover approach. Would that be Miles, of Go Below? It turned out not to be. Instead it was a chap for South Snowdonia Mountain Rescue, scouting locations for an exercise. Having bumped into us he wondered if a shared exercise would be in order. We thought it would! But we also thought the midges were getting unbearable so we parted ways; we wanted to get underground, where the midges don't go.
Discussing with the MRT chap
We explored one entrance, which contained some machinery, a loaded-up cart, and a fallen-over crane. Nice! We also spent some time just lying around and looking at the darkening sky and eating apples. A relaxed night! Another entrance allowed us to drop a level. It went a fair way! I didn't try to take pictures in that part of the mine; I didn't have my tripod with me and the chambers were huge. But it was enjoyable.
The fallen-over crane
Some of the best sleepers I've ever seen underground
Pretty much everytime you see a spoil heap on the surface it's worth checking underground! Which means I still have a LOT to explore...
