curious if anyone considered using a huge air stone like in a fish tank to send bubble up from 10x. Using an air filled bladder to seal off above the waterline and an air line fed down sending tiny bubbles up to surface no matter the path it will surface along shore source. Low PSI High volume air. 2nd I see the cave in pit to be more than nothing. 3rd. in old photos i see the deep pit dug last season with tunnel shooting toward money pit area. It was all exposed back in 1970 photo of smith cove. 4th the newly shown possible forge in lot 15 area should have a tunnel stemming off its location. It is the way to pull out bad air from deep down below. Fresh air would enter elswhere. The forge heat pulls air up and in right layout a nice fan source. They lived on the island for years to get this done. whatever it was that was done took a long time. Food and sustainance tools and those to make them is needed for many people, clothes etc. 5th the stone paved area was used to dismantle boats for tunnel timbers. The huge fires were needed to keep warm its cold up there and they worked year round. In winter the sea was frozen and could dig smiths cove. tunneling granite or ice granites harder. They had to work year round.
