In an effort to post something other than how to tie bolt snaps , here's a brief report on our intial exploration into a flooded mine last weekend.
Product mined: copper
Last worked: ~1930
First dive: unknown, no evidence
Max depth: 91ft and still going
Water temp: ~42f
Our first foray, max depth 91ft, runtime 20mins, 120ft of line laid, basically a near vertical shaft 4ft tall x 8-10ft wide, timbers for sliding up ore on the 'floor', ladder on the west side, piping and pumps along the east edge.
