A friend of mine put this video together over the course of several dives we did together recently.
The place is called the Piquette Mine in Southwestern WI. We regularly dive this site for fun, for research (there is some interesting bacteria growing inside in places) and for training.
There is no sound, but hope you enjoy.
Water Temp?
Cold! Barely liquid ice :-DQuote:

It's nice because it doesn't freeze over so we have year round diving!
Thanks for sharing.
Thats pretty awesome, thanks.
John did a nice job on the video, as usual. Thanks for sharing!

Isn't there some concern with the fact that it's a lead mine?
No, the water is clean (it's been checked). I probably wouldn't drink it but it is clean. One of the reasons is because of the bacteria, it tends to use up any bad metals in the water. It is pretty neat!
This one was lead and zinc, but we do also dive some that were just lead.
Some of you might recognize that location as the same place I entered in the holiday photo contest, without the snow of course. The 50 degree water feels downright comfy when the OAT is about 10F.
Nope. Bonne Terre Mine in Missouri was an old lead mine. When I was there, we asked the same question. They said lead in its natural form is not toxic. After it is smelted is when it becomes toxic.Quote:

Cool video & nice technique too.
