Later some governemnt agency tried blowing them shut for safety,
and did sort of a half-assed job, leaving a handfull of shafts open, even more dangerous
than before, as a mess of semi-collapsed timbers and rubbly partial openings. So those were
the digs me and my friends explored when I was a teenager. These pictures are just a couple false
start tunnels that don't go anywhere, but approximate what the sandstone tunnels were like.
