I would consider this "home" quarry. I am from Ohio and have been diving here since my 3rd and 4th certification dives for the last 5 years. I use it for practice dives before and after boat dive season on Lake Erie. There are 2 entry points. The first is walk-in and used by classes. Very easy! The second is a platform style deep entry where they just added a ladder this past Spring. Again very nice entry/exit. The bottom is limestone and the main floor is 40 feet. There are the remains of the crusher going down to 70 feet and a tunnel that is off-limits. There are piles of stone rubble on far end by the deep entry on which an old police cruiser is perched. There are several "wrecks" and a step-van that used to deliver for the Frito-lay Company. The vis can vary widely from the spring to fall and from weekday to weekend. I have seen it as high as 50 feet in the Fall on a weekday, to around 10 feet when there have been classes all weekend in the Summer. There is a dive concession there during the weekends during the Summer offering air fills and snacks. The "facilities" are outhouses, but there is an area for changing. It is a great place to take students (I am only a DM, but I assist there a lot). I also like to go there during the week just to enjoy a relaxed kick back dive.
