This cache is hidden under the stairs on the west side of the four-story crusher house and is about 25 feet underwater. Scuba is required to access the cache. Please do not attempt this cache without scuba gear and appropriate training. Do not put yourself in any undue danger to hunt this cache.
This lake is the site of a limestone quarry that operated from 1937 to 1977. Yep. That hole took 40 years to dig. The property is now open to scuba divers on weekends most of the year. As is common with scuba diving quarries, there are waivers and entrance fees. That's no surprise. What may surprise you, though, is the clarity of the water here. I have personally seen thirty-foot visibility. That's just crazy for an untreated freshwater lake in this part of the country.
Depths approach sixty feet in places. It'll be chilly down there. Late in the summer, after all those long, hot days, the water may be 85 degrees down to the depth of this cache.
So. What are you looking for here? Well, it's a 30 cal ammo can painted to look like a diver down flag. It contains a dive slate for the logbook. Bring your own pencil -- you wouldn't want to use one that had been underwater for a year, would you?
After some discussions with reviewers and other cachers, I've decided to mark the Difficulty as less than 5. Sure, "special knowledge" could qualify it as a D5, but that special knowledge is required just to use the scuba gear (safely).
NOTE: The quarry is open on weekends throughout the year.
