While at the ODL big spring event I fancied some underground work so I hit up UCET via Facebook and did these two mines. The first was an SRT into a steep adit with lots of side passages, one leading down to a lower passage, and then a step across to a passage back out to the surface, entered from surface higher up and exited again via entrance rope. The second mine visited after a drive had a walk in level, where after a while a SRT route dropped down 3 pitches (second very loose) into a deep level where I braved the deep chest deep water to reach a blockage very close to the surface, which had some spectacular mud formations (before the wet bit).
