Cameras welcome for trails 2 - 24, just not on trail #1.  The DM explained
that he prefered divers pay attention to the site and procedures rather
than fumbling with a camera. No specific facilities for UWP.

Easy dive, but challenging due to conditions.  This was an active mine some
350 feet below ground, until they turned off the pumps.  Crystal clear
water; no fishies or anything else swimming around--just divers.  Some
areas have overhead lighting; this could be a night dive at noon if you
turned off the lights.  Cold water, constant 58 degrees Fahrenheit . . .
dry suit or 7mm, with gloves and hood (rentals available).  Unlike reef
diving, divers were allowed--encouraged--to touch things in the water
(tools, rocks, ore carts, etc).  No muck or silt to stir up.    Divers must
dive the trails in order (i.e., 1 through 24); your logbook verifies what
you have done.  I dived trails 1 and 2; other trails promise to be much
more interesting.  A bit expensive at $65/dive with a 2 dive minimum. 
Weekends only; popular winter dive site.  Guided tours of 10 - 15 divers +
guide + safety diver.  DiveMaster James M. was a first class guide; very
professional.  Go to for more.
