This former quarry is now a county park and is less than 2 miles from my house. It has very deep and pristine clear water. Warm and clean and ideal for practicing self-rescues, paddle swims, braces and rolls. I spent some time here with Guinness this past late summer, and often paddle it alone. Clean water is becoming increasingly rare across the USA, and the Midwest is no expection. It is a pure joy just to be on--and in--bathtub clear water.
